The Quix lowering speed, plus Lira's haste are big when combined with a Creeping Ooze. Your offense can move them down while they watch. The catch is you need to have Quix and Lira at level 3 to be able to run this, but in the meantime Quix with the Ooze are great too. Lira without haste isn't that great, but the Death splinter is certainly one I play a lot. I just upgraded my Water and Death summoners to L5 Gold last night to take more advantage of the added abilities which make it such an effective splinter for me.
