Bronzehide Lion

Kill it once and it doesn't go away: it comes back grafted onto another body. That reincarnation is the design's whole trick, and the clever part is that the returned Aura carries the exact same activated ability as the creature side. Pay two mana, shrug off destruction and lethal damage, whether the Lion is a beater or an enchantment stapled to your best remaining creature. The death trigger rewards a developed board, since the Aura needs a host worth protecting; as a lone threat, the rebirth is anticlimactic, but across a full battlefield it turns a survivor into something that walks off wraths and blocks all day. The whole card folds two of green-white's oldest instincts, a resilient aggressive body and a repeatable protection spell, into a single two-drop without asking for a second card to do the second job. The limits are worth naming plainly, because indestructible only answers destruction and damage: exile, bounce, sacrifice effects, and minus-toughness still take the Lion (or its Aura) cleanly, and the reborn Aura trades away the ability to attack. What you get is a compact study in how to make a cheap creature survive removal twice while still costing exactly what a 3/3 should.
