What is the dumbest thing you've done in a game?

In Kaldheim, my opponent had just cast and kicked that equipment that put a 4/4 flying angel in play. I smirked a bit, then cast my bounce spell, carefully hovered over his creature, and **BOUNCED THE EQUIPMENT BACK TO THEIR HAND** giving them effectively another 4/4 at a cost of one card from my hand.

I have one actually, reminded of it when you said you'd conceded. In this one I DIDN'T concede and somehow won the game.

I was playing UR spells in Dominaria United quiick draft. My deck wasn't exemplary but it could win.

First match I had Battlewibg Mystic in my hand, which I decide not to play on turn 2 because hey, with kicker it's a 3 drop anyway. I kick it on turn 3.

I clearly had not read the card properly. It is NOT a turn 3 play. I promptly discarded 5 or so cards and drew 2. My hand had not been terrible.

As it happens, I rode the Mystic and the Flowstone Kavu I drew off it to victory. My opponent wasn't doing a lot, but it still felt good.

In a lotr game I was at one life, but had the win on board. I attacked for the win and decided to fire off a removal spell to (needlessly) kill the opponents easterling vanguard for no other reason other than to play a card I guess. I had forgotten the opponent had a mirkwood bats in play, and lost the game.

Ok so they can’t attack with their big creature because they’re scared of my 1/1 frog being activated. I need to start getting damage in though. If I attack with creature one, no that won’t work, creature 2? If I had a pump spell I could. Oh! They’re scared of my frog I’ll attack with that!

Proceeds to attack with the frog with only one mana up and I can’t give it death touch and they chump with something worthless.

I attacked with a Stinging Cave Crawler with Descend active while I was at one life. If I hadn't attacked with it and just hit with my other creatures, I would have won the game that turn.

Idk why but when I play live I constantly forget to craft from the graveyard and end up sacing tokens or something instead. Not even once I've done it at least 4 times

Besides just accidentally losing the game via pinging myself or something, yesterday I attacked all and left myself dead from the crack back. But I must’ve been so bold my opponent tanked and did not attack back.

They literally had it and I was tapped out.

So I untapped and attacked again to win. I wonder if my opponent saw they had the win later.. it really was just their power vs my life, everything was tapped.

In Wilds of Eldraine, despite having a very clear path to winning, I managed to lose a game by pre-combatting removal not one, but TWICE, against a [[knight of doves]]. For reference, I had lethal flying damage on both occasions with absolutely no reason to precombat the removal.

I cry every time I think about it.

I have made a lot of bad plays, but this one really stuck with me because I showed my opponent my out but didn’t see it myself.

NEO draft. In a game of attrition we were both mostly out of action. Opponent tapped down my blocker, and attacked with a small flier I think equipped the [[Armguard Familiar]] that has ward to finish off my last couple life points. One of us has a creature under a [[Tamiyo's Compleation]]. I have [[The Wandering Emperor]] in hand and enough mana to cast it but not enough to pay for ward.

I sit and look for a minute and resign myself that I can’t make a blocker or exile their attacker. I cast Emperor and then concede, and then immediately see that I could have exiled the compleated creature to survive with Emperor on board, and probably go on to win.

Mystery Booster draft. I'm at 6, my opponent is at 8. I have a [[Blighted Bat]] and a [[Swarm of Locus]], they have some 4/4 with no relevant abilities and an [[Oracle of Nectar]]. I have nothing relevant in hand, and there hand was either empty, or they were holding up a basic, but it was a spot where assuming they had nothing was a pretty safe bet.

I draw a basic, and reason as follows:

If I hold back my Bat, they'll use Oracle of Nectar, and I either chump block the 4/4 or go to 2. So they're suddenly much harder to kill and I'm facing lethal on the turn after that if I don't draw anything either way.

If I hold back my Locus, a similar situation, but then they can choose to force me to chump if I desire.

If I hold back both, it's basically still the first situation.

I need to pressure their life total before Oracle of Nectar takes them out of range.

So, I attack them with both my creatures.

Incidentally, I won this game through some very lucky top decking, but that would have happened whether or not I left my opponent the opportunity to just attack for lethal.

Ohh, I got one. Competitive Rules enforcement. Side event at a GP.

Forgot to play my turn 1 land.

Too busy chatting with my opponent. Didn't even realize till it was my turn...

Still won the game somehow. But I felt real smart that day.

Not the dumbest, but most recent. I punted a game yesterday and I need to rant about it. I have sunborn (the red/white uncommon) in play. It's 5/5 because it explored some way or another. I also have a sunfire torch and another random artifact in play. I'm at 2 and my opponent has like 5 lethal creatures in play, so I can't possibly survive the next attack. They're at 4 with two untapped 2/2s in play. I'm tilted because I was so close to winning that game earlier and I just got a string of bad draws while my opponent drew perfectly. So I just yolo attack with sunborn and tap my two artifacts to see what crap I'm going to cascade into. I cascade into dreadmaw's ire, which makes my creature into a 7/7 trample, they double block it, they go down to 1, they kill me next turn.

If I'd just equipped the torch, that would have been lethal.

I really should have spent half a second to think what my outs were. Ire was one, but I also had an abrade left, so if I had hit abrade, I could have killed both blockers. I even thought about equipping it first and then thought "heh... why waste my time? I just want to see what I cascade into."

On a sidenote, if you have both sunborn and the torch, make sure you enable manual trigger ordering and make sure you pay attention to how they're ordered. You want sunborn to trigger first if you want to sacrifice the torch, so that you get to tap it before it's gone! I felt like in the past, the "default" order was generally good, but in this set, it's often suboptimal I find. For instance, if you attack (or tap) both volatile wanderglyph and attentive sunscribe at the same time, it puts wanderglyph's ability on top of the stack, which is weird. I'd rather scry first, see what's on top before I decide whether I want to rummage. Even if I know I want to rummage, I'd rather remove any potential land that's on top first.

Goblin tomb raider and sun fire torch. Sac’d the torch on attack targeting opponent to deal exactly lethal counting expected combat damage, except I counted as if the goblin would drop to 2/2 (thinking its own ability checked on attack). Instead dropped down to 1/2, as I had no other artifact, and left my opponent at 1. They stabilized and won the game from there.

Yesterday I paid my last life to a painland

I had two consecutive lethal swings that I ruined by casting my buffs pre-combat against the “you can’t attack after casting a spell” creature in LCI. I resigned after the second one

Playing as if craft only applies to onboard permanents, and completely forgetting that I can use the graveyard. Urrrgh...

Named the wrong Jodah with anointed peacekeeper in DMU. Went from a guaranteed win to him popping off like crazy and stomping me.

To make matters worse it was my mythic promotion game, and after losing I went on a terrible skid.

It made a dumb punt feel soooo much worse.
