Well, Enduring Enchantments has card draw to back that up, and one of the reasons it makes it to this list is the platform it provides
Core mechanics include morph , sacrifice synergies , and strategic removal that complement the decks theme of hidden threats
Obviously, if you have graveyard synergy, flashback, or cards you want to discard, the effect is all upside, but you don't have to go this far
Play progresses over a number of rounds (called tricks), and in each round a player starts by playing a card of a particular value and suit
If you proliferate twice, you don't have to choose the same set of players and/or permanents to get additional counters each time
Zeus should really only be played when you can immediately pay his Boost cost and survive
