Card first:
Bop's Paradise
Land

: Add

to your mana pool. Bop's Paradise deals 1 damage to you.

,

: Add one mana of any colour to your mana pool.
Green deserves some better colour-fixing, I think. 5-colour decks can make good use of green as a mana-fixer, and this one does that in a hopefully-not-too-good way. The first ability does green instead of colourless mana because otherwise it wouldn't work very well with Birds and would be a weak first turn drop, in my opinion. The damage might add up with fetchies/painlands/Ravnica duals, but I think it's worth it.
