And the first place you can try it out is during the WPN Premium Preview Weekends starting July 1, followed by everywhere else on July 8
Bedlam is a 4-mana red enchantment from Urzas Saga that states, simply: Creatures cant block. That's just about the long and short of it
This is because even if your attackers were to perish in combat, Rienne returns all multicolored creatures that died under your control to your hand at the beginning of the next end step
Like the combo that I'll give you below for you to start your Aeve deck: Temur Sabertooth will return your Eternal Witness to your hand, which will continually recycle your Early Harvest, generating as much mana as you want, which you can repeat this combo, will trigger abilities of permanents as many times as you want and will increase your storm count to very high numbers, creating thousands of Aeve, Progenitor Ooze tokens and making them all gigantic
Every spell you cast this way will replace itself (and hurt you slightly), which means you'll basically never run out of cards if you can keep the Treasure generation coming
A turn one Ragavan offers both ramp and potential card advantage off of whatever player it hits
