Much of the deck is designed around mechanics like escape, cascade, flashback, and escape, letting you get multiple uses out of your spells and giving you all sorts of 2-for-1s to get maximum value out of them

Or you might draw on the WBG combos that let ramp your way into a few huge creatures, like Looming Altisaur, or Indomitable Ancients. Or you can mingle those strategies: perhaps you summon a Watchful Radstag early game, which both grows bigger and spits out token copies as you pop out mid-range creatures, then pimp out those tokens with a Canopy Gargantuan and keep Scour the Desert in hand to flood the board with a token army if all else fails

Whenever a creature is brought from the Graveyard to the Battlefield, every creature you control gets a +1 counter to both Power and Life
