So we have Gambit as Death already

could have Dazzler borrow Sunfire's stint as Famine. Letting her light make people hungry would be workable.

Banshee could borrow from Polaris as Pestilence. Letting him infect people just by screaming at them would be neat.

Which leaves War.... and I chose Tommy. given what happened... Tommy would want it. Offensively using the 2-d shifting thing.,... oooh... that could be fun. Oh also blood-rage aura, to make enemies think... poorly.
