This is no joke. Wizards just ruined Magic with a Sixth Color. Take a look:
These are all legit. They’re even on Mythic Spoiler. This new color is exclusively colorless mana. It’s acts like a sixth color. This is crazy. Be prepared for a rant. Why? Why Wizards? You are ruining Magic. R-u-i-n-i-n-g i-t. We don’t need this color. Wait a minute. It’s not even a color. It’s exclusively colorless. I really hope that this color is only for OGW, otherwise I would die. I’m seriously thinking about not playing Magic while Oath is in Standard. This is stupid. WHY WIZARDS? WHY???
Ok. Rant Complete. It’s not really THAT bad, the flavor is pretty good, but this is going to be hard for deck building. If this is going to be in the next set, let’s talk a little about the cards. A return of Kozilek is nice, but Kozilek is seriously underpowered compared to Ulamog. It’s first effect is not that powerful. Menace is nice, but not game-changing. The last effect is OK control, but discarding your own cards as counter spells is not really a competitive effect. Two reasons I don’t think it is flavorful enough. One, it doesn’t exile anything, a big theme with Eldrazi. Two, it isn’t Indestructible. That is pretty much a must in Eldrazi Titans. Mirrorpool is a pretty good utility land. If the Wastes mana on the card was colorless, this would be a powerhouse. Right now, I’m not sure if playing Wastes is worth it. The utility effects are very good and effective. Kozilek is a disappointment, but Mirrorpool may be playable.
