I'm missing some lingo here, I don't know which card is "Dead Mike". Morphling is basically filler, I don't recommend it unless you've got nostalgia. Rainbow efreet has little advantages that make it legitmately useful (plays nice with sweepers, can be run out early to block in an emergency). I run Rainbow Efreet and Morphling as a blue finishers and they both get played.

I think he'll slot in for a while again soon. 6 mana semi-evasive superanthem is an awesomely awkward effect. I think he would be an excellent alternative to Grave Titan, I just haven't made him work, most likely because I don't support any combos that use him.

He seems awesome, but he never seems to make the main deck. Isn't Massacre Wurm a win the game finisher more often then not? However, it doesn't neatly support any specific archetype, so I could see not running it. I will never run Balance, but I also will probably never cut Cataclysm. This card does work in a lot of different decks and requires careful attention to sculpt the gamestate to where it is awesome. Its very, very different and the advent of Planeswalkers has only made it even more intriguing. Its not strictly a finisher like Armageddon though. I've run Cataclysm since it was printed and love it.
