Getting rid of problematic cards from yards on ETB or attack is spicy
Amusingly, your opponents will probably need a non-creature spell to take it out, so you might get one last draw on the Sentinel's way out
Most people exclude these from their value lists as they are so well known that they form the core nine of any standard top ten list
Pairing this Simic card with another token doubler like Doubling Season can get serious numbers of tokens onto the battlefield
It feels weird to wrap things up with a Sance Board, because usually things start to unravel when you get one of these out, but here we are
Granted, this path and the ones involving tokens lean a lot more in the combo direction than the mana acceleration direction, but its definitely worth noting Carnival of Souls capability of being useful outside unreliable 3-4 card loops in these strategies, as it gets a bad rap Im not convinced it fully deserves when reading about its capabilities elsewhere
