I beg someone to disagree with me on this. The Anti K' is I honestly believe currently the most game defining card in all of block 2 and soon to be block 3 UFS. Every single deck has to worry about what they play first turn less they get time walked, it is one of the few cards that can punish someone for going first, its a great stop to early Feline spikes because often they will be forced to commit down a foundation they needed to push though the spike (and devistating against 6 HS spike Felecia), and it lets you flush unwanted cards from your hand. in a pinch it can even nuke a block (action or foundation) on a game winning attack and its 1/5 with a printed block too boot.
When building decks latley I will often consider what my foundation base looks like and often side with lower power / lower difficulty cards just to get a better curve in my build that can pass my checks with at least +1 in case i face Anti K. Often times its the only card ill splash in what would be an otherwise mono symbol deck. Even when the card winds up being usless junk against on opponent in a tourney who gets lucky and gets out a destiny turn one or is playing galford, it's still not a wasted card based on the other matches it wins me and even with Ocladans being in every single deck Ill still run it in everything.
I honestly feel that in block 3, this card DEFINES the entire block of cards and helps shape the game more than anything else. Discuss.
