Pay : Put a +1/+1 counter on this creature
If youve been itching to mess with your opponents a bit and make the game a little harder for them, you might want to consider picking up some of these hexproof creatures, all of which can keep you in the game or sneak through some damage to speed up the game
This can also pave the way for players to use some of the best and rarest Magic: The Gathering cards around, and it's why new Creatures with Partner may never be printed in the future
