This card engine is a bit more restrictive than Bolass Citadel since you need sacrifice fodder to get your cards rolling, but should you succeed in doing that, Yawgmoth becomes a card capable of taking over entire formats
At the beginning of the next end step, if any of those cards remain exiled, put them into your graveyard, then create a 0/1 colorless Eldrazi Spawn creature token for each card put into your graveyard this way
3 Ninja Teen Enchantment Class The return of the class cards has been successful so far, with Ninja Teen being another great example of how these cards can really improve a deck and swing the tide of battle if left to upgrade without removal
There is also a niche tradition of decks leaning into Pacts weirdness, either by nullifying its lose-the-game trigger, or better yet, foisting it onto their unsuspecting opponents
At the start of combat, on your turn, you get to bolster for each differently named artifact token you control
