Going to try out standard, having some anxiety.

I started magic on tempest and played through onslaught and sold my collection back in 2005, I then got back into EDH just before FF release and have been super addicted with some Arena (bo1) mixed in.

I'm very interested in trying out standard but am very worried that the bo3 sideboard format will ultimately give lots of anxiety. I understand that's the way it's meant to be played, but I'm so used to the old days of cafeteria/library/friends house magic when we just did our main decks and have never dealt with sideboards. I don't know why it's so daunting to me but I am afraid what I have will just get laughed off the table or I'll just get bullied because I'm unfamiliar with swapping pieces in and out to deal with other decks.

I finally threw a deck together, I LOVE reanimate and graveyard synergy and am curious if what I have will even survive at FNM.

Unfortunately I have nothing in arena I can try and practice with in bo3, so FNM is where I'll have to test my mettle.
