mtg hydra cards Broodmaster - Single Card Voracious Hydra fights target creature you dont control. Mossborn Hydra · Foundations (FDN)
Description
First draw only: If you draw multiple cards, they're drawn one at a time

So, if thats the only card in your hand, you go to ninjutsu it in, and your opponent can make you discardthen you wont have the creature anymore to make the swap, so it wont happen

While this card isn't cheap, it's far more affordable than the most valuable Charizard cards in Phantasmal Flames

That said, keep in mind that historic bias means the same player who doesnt pay for Rhystic Study might pay for your spiky dude, and it will be super annoying
