the closest thing we get to a cubeable combat trick
Preach. Combat tricks are a staple of traditional limited sets, and the fact that we don't have a single cubeable one bothers me. Unfortunately, I don't think this card even comes close to cutting it. If only the mana cost was much lower. Something like 4R and Equip 2 would have made me want to test it, but alas this is just too expensive.
Maybe some day.
Mutagenic Growth is really good. It's a free spell for the Young Pyromancer/Monastery Mentor/Kykar decks too.
Mutagenic Growth is just great. Free spells are nutzo in the spells decks and hyper aggro love it too. I also play berserk and temur battle rage. Both make Kiln fiend one of the biggest 2 mana threats in my cube. Maybe not for everyone but I am shocked no one else likes them. They are gorgeous with equipment.
As for this card. It's kind of a garbage fire win more card. The kind of decks that want it don't want big clunky spells. Token decks need more walking anthems, Red god type stuff, and better things to do before turn 3. My problem is not how much you end up paying for this just hat it isn't happening until turn 4, at which point I just want a hellrider or Armageddon.
