I tried to build an EDH deck specifically around each of the original Elder Dragons.
Chromium has Rampage: 2, which isn't a particularly useful ability. It's based around blocking, so I made the deck around "blocked" / "blocked by" abilities.
- When this creature is blocked, draw (or some other effect)
- Deathtouch / Exiletouch
- Choose how creatures block / Lure effects (only a few cards in B/U/W) / Provoke
- Can block any number of creatures
