Rainy Days

Fading X
Each land is an Island in addition to its other
land types. (They produce {u} or mana of their
original basic land types.)
Sources that cost {e} that targets attacking or
blocking creatures may target any creatures on
the battlefield instead.
If a blue source would deal damage, it deals that much damage plus 1 instead.
If a red source would deal damage, it deals that much damage minus 1 instead.
