Fun with Allies

My friend came up with a nice allied combo deck.

It's has a bunch of fun stuff with all the allies triggering each other via Spinter Twin, but my favorite thing he does is this:

Harabaz Druid + Crab Umbra + any 3 other allies (which is really easy with Twin, 1 drops or join the ranks)

1. Tap the druid for 4 Blue mana.
2. Activate Crab Umbra using 3 Blue mana, leaving 1 floating blue.
3. Repeat infinate times to max out your blue mana pool.
4. Tap druid for 4 Red mana.
5. Play banfire for infinate.
6. Laugh.
