One thing I like to do for my team's elimination partners is to do a button swap with out partners. Attached is a picture of the buttons of all the elim alliance partners 1511's been this year except at champs. (Champs was chaotic and I forgot to try to get them.)
Also With regard to alliance buttons and logos I put together
a gallery of the 2013 World Champion Sticker which combines all three logos. It's pretty cool to check out.
Also as a spirit activity we like to create an "alliance name" for the MC to announce before elimination matches. At Finger Lakes the alliance name was "Rolling TanX of Wrath" (1511 Rolling Thunder, 3003 TanX, pronounced tanksm and 1551 Grapes of Wrath) and at Beantown Blitz the alliance name was "Red Thunder Hawks." (4048 RedShift, 1100 T-Hawks and 1511 Rolling Thunder)
