Venat, Heart of Hydaelyn // Hydaelyn, the Mothercrystal

The design gamble here is putting a repeatable draw engine on a three-mana 3/3 and then charging seven mana to flip it. The front face rewards a deck built entirely out of legendary spells: one card per turn for casting the kind of legend a legends-matter deck already wants to run anyway, which is close to free value in the shells that can support it. What keeps that from running away is the once-per-turn clamp; you cannot chain draws by stacking cheap legends into one turn. The flip is the tension. Hero's Sundering is unconditional exile of any nonland permanent, the cleanest kind of removal there is, but it costs a full seven plus a tap and only fires at sorcery speed, so it functions as a slow, expensive answer rather than a combat trick or a stack response. Flipped, the payoff is Blessing of Light: a beginning-of-combat counter distributor that hands out indestructible and, crucially, replaces the front face's spell-triggered draw with a body-based one whenever the target is itself legendary. The whole card is a bet that a legends-heavy deck will keep both draw triggers live across the transform, so the same engine survives the flip rather than resetting it. Indestructible on the back half means the removal you just used to earn the flip is hard to answer in kind.
