First try.
Citron is not the spud you make him out to be. Recall, he is featured on the zombie mission 200/200 and shares a typing with Beta-Carrotina.
Sure, its kind of silly to feature a card (Mayflower) and then pair you off against an opponent with 1/2 superpowers and 4x 1-cost Zombot’s Wrath that destroy it. That seems like a bit of an oversight... but is far, far less bad than (that is to say, better in the bad department, not worse, an improvement, not nearly the same snafu as) an unsolvable Puzzle Party.
I like Citron > Beta, personally, in this match-up. Gotta Transmorgrify those Gargantuars and just say “Peel Shield” to Frenzy.
