It is, if you don't plan to only use phoenix effect. I'm waiting it for my Sphynix deck. This monster effect is good enough imo. Importantly, it's damage-step/both player-turn/atk mod. If you really need to active phoenix effect, you can summon its from the grave and destroy it by effect on the field by the old set of card. This card just like free search card of soul without lp restriction.
