Effects that prevent damage dont work against extort
Both sides of this red MDFC are compelling enough for this strategy to value it highly
In this case, if damage would be dealt to a creature the turn Gatta and Luzzu entered play, G&L will replace that damage and put +1/+1 counters on the creature instead
Both vintage and modern Pokemon cards follow this system, so the age of your cards wont play a role here
The War Doctor tracks each individual card that gets exiled or phased out, so effects like cascade can quickly rack up counters on The War Doctor, potentially even enough to take out an opponent in just one attack
Black and red together make creatures that dont just attackthey also mess with your opponents life, cards, and board
