Yathan Tombguard A card that cares a lot about creatures with counters on them is Yathan Tombguard
I wouldnt prioritize it over more efficient/synergistic cards though
This offers a good buff for the cost and has a very, very strong combat damage trigger
First, there's a new mechanic called Sneak, which is a riff on the pre-existing Ninjutsu, in which players can cheat big creatures onto the battlefield whenever an attacking creature goes unblocked
In summary, this set is definitely going to shape the game going forward
You can put both triggers on the stack, then resolve Displacer Kitten's first, have it blink The Fourth Doctor, then trigger The Fourth Doctor and generate a Food Token
