Certain cards like Mufasa and Elsa can significantly impact gameplay by offering powerful abilities and lore-generating potential
The short version of it is that there is a balance between how much time (read: mana, turns) one can spend accruing cards while contributing to the battlefield
Here, my opponents decision to cycle a shark in to block my Familiar was punished by this sequence: play second Oven, sac second Familiar to get my third food, reanimate Feasting Troll King, cast Great Henge for just two mana, tap it to cast Uro and trigger Henge, sac Uro to second Oven (with his triggers on the stack) for two more food, use food to reanimate both Familiars (two more Henge triggers)
