So what are these serialized cards
Its also not fun (the 3 will beat the 1 every time)
As soon as Decimator Beetles ability resolves, state-based actions are checked, and the game sees that you have both counter types on your Servant, so one +1/+1 counter and one -1/-1 counter are removed at the same time (resulting in Servant dying)
Its price is steep at , but giving every vampire that hits your side of the field bloodthirst 3 is more than worth it
And when Liliana transforms, she makes a 2/2 Zombie token for free, and thats a great bonus
It is very similar to Yunas ability, but its arguably more powerful as this is an enchantment so it cant be destroyed in combat, and its in play anytime a card goes anywhere, not just the graveyard
