Mecha Dragon

How the text actually reads

Cooldown shrinks as it upgrades: 6 seconds, then 5, then 4. Multicast is 2 at every quality I can see on the card. Using it enchants it, so the enchantment slot is not a one-time shop decision; the item keeps rewriting that slot. Nine merchants can offer it, among them Goldie, Barkun, Valpak, and Silvia. Price ladder is the usual large-item 12 / 24 / 48 gold. No monster drop is listed.

Buy it when you are already on The Dragons and you have other flying or tempo pieces, because a self-enchanting multicast is wasted on a board that never wanted enchantments. Cymbal is the cheap instrument that spends tempo; Mecha Dragon is the body that wants the enchantment payoff. They are not substitutes. Skip the card on Mak: the hero tag is The Dragons, and Tomb of the Ancients will not multicast just because a dragon is nearby.

The 6 Nov hotfix does not name this vehicle. History versions exist on the card without a sentence. I leave the diff column empty rather than guess that "enchant it on use" was the November change.
