I enjoy deck-building as it's a good creative outlet. Been getting a 40-45% WR at UB3 with this deck. Of course, being 4 energy with no ramp means maybe it's better to just run one copy of it, though it still plays a key, central role to the deck.

I saw some posts on how bad Gigalith EX is, but it's actually really hard to balance when you're doing 140dmg to the bench. It can 1HKO many EX pokemon, or set up a Cyrus kill for a Mega EX in the next turn. In other words, it HAS to be hard to set up or it would be rather OP and super annoying since it shuts down so many plays and deck styles. If you already have 1 point from Falinks getting a baby or other basic mon e.g. Meloetta, and there's a viable EX target on bench such as Indeedee EX, then having even 2 energies on Gigalith EX might be enough to secure the game. Gigaleth EX is tanky (moreso with ice pop and cape) so it can buy time for itself as you add the other 2 energies. Honestly, with ramp, this would be super annoying (possibly OP?) to play against. 

Even if it doesn't deliver the winning blow, if it takes out the hard hitter on the opposing team, it can usually tank a hit or two (or 3 with cape and ice pop) from the supporting cast mons, and there's also the option to retreat (with energy) for Rampardos to clean up, or do the ol' Lyra fossil switch for a second Megaton Cannon (super satisfying to land)!

Yes it's not as consistent as the absol+hydra, greninja+any and other meta decks, but it allows for a rather unique playstyle that might entertain you for a bit. Any ideas for improvement? (Also wonder if there's any madman that will try to set up two greninjas alongside this guy for maximim troll.)
