Trickbind would only stop
Pili-Pala from becoming a blue creature for one turn. If the opponent misses the window, then
Trickbind is useless. It's the least of my worries. Yes, in some cases one turn is enough disruption, but often times I'll just combo on my next turn - or if I have a blue mana available, on their upkeep.
My concern with Kira, is it does nothing against
Abrupt Decay. Jund is already a bad matchup because of
Liliana of the Veil.
