Spellstream Elemental

Spellstream Elemental enters the battlefield with
a +1/+1 counter on it for each instant or sorcery
spell you cast this turn.
Spellstream Elemental can't be blocked and has
haste as long as you cast three or more instant or sorcery spells this turn.
Quick as a fleeting thought in a chemisters' head, it
flows through the massive currents of arcane energy swirling through the Izzet League.
