Current testing has shown that the deck works about as intended, but has issues overcoming decks that also try to swarm with smaller creatures quickly, since the defenses and spells that are in place are designed to counter fewer, stronger creatures (Ghost Jellyfish, Impel End).
I'd appreciate any suggestions on how to offset the weakness against other swarm-type deckbuilds, or how to optimize my capacity at overwhelming other deck types, or just suggestions in general since I'm still new to this online card game thing
