Draft note
Treat Drum of Battle as a signal card until the surrounding deck has enough payoff. It should not be evaluated in isolation from Ironclad scaling and relic support. The right question is whether the deck can use the card on the turn it appears, not whether the finished build would love to have it later.

Support density check
If the run already has the pieces that turn Drum of Battle into a payoff, the card can move up quickly. If the deck still lacks damage, block, draw, or relic support, it may be better to take a simpler card that wins the next fight.
- Count existing enablers before calling it a build-around pick.
- Compare it against immediate damage and block needs.
- Use Ironclad build pages to decide whether the package is actually open.
