Hellkite Charger A dragon that attacks with haste is already a good choice, and one that has a late-game ability is even better
Commander Mustard has a passive ability, giving your other Soldiers an impressive array of keywords, vigilance, trample, and haste, turning them all into threats
For punctual removal, we have Infernal Grasp, and in case you are the target of a massive attack, Aetherize will solve your problems
At six mana and not actually having native hexproof, this flying Dragon presented me with a deck-building puzzle that I was happy to try to solve
EOT you get a free +1/+1 counter on it if you descended, and with trample, that should win pretty quickly as you focus on growing this for a win in the Red zone or to finish off wounded players
it does play better in a value deck, where you are focusing more on building board state and rebuying cool creatures and effects with it
