Bello, Bard of the Brambles
Expensive artifacts and enchantments tend to buy an effect and nothing on the board: a big engine piece or build-around costs its controller a chunk of a turn cycle before it justifies the spend. This flips that math into an incentive. Every non-Equipment artifact and non-Aura enchantment you control at mana value four or greater becomes, during your turn only, a hasty 4/4 that refills your hand on connection. The keying is aggressive by design. Value is stapled to combat and to your own turn, so there is no chump-blocking on opponents' turns and no exposing your engine pieces to a sorcery-speed sweeper when it hurts most. The indestructible clause matters as much as the card draw, because it lets a costly mana rock or enchantment engine attack without wagering the permanent that pays for the deck. What is clever is that it demands no dedicated creature base at all: the deck's mana value floor doubles as its threat count, so a pile of high-cost noncreature permanents that would otherwise sit inert reads as a squad of undying attackers. Two restrictions keep it honest. The base 4/4 override means nothing gets bigger than 4/4, so oversized bombs are shrunk rather than enlarged, and there is no granted evasion, so those 4/4s still have to swing through blockers to draw. The four-or-greater floor and the Equipment and Aura exclusion aim the whole thing at standalone permanents rather than cheap rocks or attachments meant to ride a creature.
