RY Haste Burn
A rush burn hybrid that uses attack buffs with haste creatures and burn to finish off the opponent. It's strong against swallow decks, since there's no good swallow targets in it. It doesn't matter if your opponent swallows a haste creature, since it already dealt damage.
Build mountains forward, then deserts until you reach your opponent's orb. Draw cards until you have a good opportunity to do burst damage. Ignore your opponent's creatures and deal as much damage to the orb as possible.
Use the Crystal Flowers to remove taunts and blockers. Summon the Chieftain only if it allows you to deal extra damage with creatures immediately.
