Can an assault swordmage combine Battlemage Readiness & Spellsword Perfection to gain a 4[W] immediate reaction whenever an enemy violates its mark?
Battlemage Readiness (11th level): When you use your aegis of assault to teleport and make an attack, you can use a swordmage melee at-will attack power in place of the melee basic attack.
Spellsword Perfection (30th level): Choose one sword mage encounter attack power that you know. You can now use that power as an at-will power rather than an encounter power.

Your blade opens a rift in reality, and you leap through to attack your enemy.
