Aurelia, the Law Above swings, blocks, and against aggro probably draws a card and dissuades them from swinging in with the fifth weenie
Jaya is control and combo, the others are basically just combo and thus very clumsy cards to have in your draws
As long as this creature has three or more +1/+1 counters on it, it can attack as though it didnt have defender
Every third card you draw in a turn after that will see you amassing another three +1/+1 counters on that zombie army, or creating another 3/3 if you dont have one anymore
You have to play the long game, and think about how you can use your resources to fight off three opponents Ill attack Gavin instead of you if you dont attack me next turn deal? is the kind of thing you hear plenty of. This shift from a duel to a free-for-all brawl significantly changes players strategies, and thus how cards in Commander Legends have been designed
The Mariner is notably quite strong against Conflagrate, a card that usually takes Humanss lunch money and one of the biggest reasons the Dredge matchup is so challenging
