I have gone with [[Island]], as this is the lowest pip density
Its pretty cheap with a 4 Mana casting cost, and with plenty of ramp cards like Lotus Cobra, Rampant Growth, and Azusa, Lost but Seeking, you could even be casting Omnath on turn 2 or 3
Playing Aristocrats and need a way to get those death triggers
Creatures are the most common type of card that can be removed from play, so naturally, creature removal is the most common form of removal
It usually ETBs tapped, taps for Whitw and you can tap it with two mana to draw a card but only if you attacked with two or more dorks this turn, which is pretty likely in a creature based aggro color like White
Once your travel plans are decided, try to apply as soon as possible
