If you are in the energy deck, however, then this is just a threat that has to be removed, preferably on the stack, before you make 10 beefy Robots that will define combat for the rest of the probably very short game
The drawback is its triple-blue mana cost, meaning almost all of your lands in your deck have to tap for blue for you to cast this card reliably
I mean, its fine, but I think if Im in equipment decks I pick other things slightly higher
It also takes up one of those few precious slots you can afford to have a non ramp, non threat card in
The TOP White ramp spell in Commander has to be Smothering Tithe
On a more positive note, I think he was the good guy for a while when Simic Flash was on a rampage, and he does shut off Embercleave, so he has that going on
