These things are so absurdly mana efficient. Like honestly wtf. Not really as much of an issue for commander, I know, but it's just crazy to me that we have a 2-drop with 3 power and toughness spread across two bodies with upside on top of upside on top of upside. A 1-drop that basically says you have unlimited clues. I have some serious concerns about MH3 in terms of power level.

That said, cards is cards, so here's my takes.

Ajani (already known ofc) is absurd on the front side in 1v1, but in commander completely uninteresting. Back side...cat tribal is awful especially without green, so his +2 kinda sucks until you use his 0 a couple times. The ult is decent but c'mon, comparing it to cataclysm is ridiculous - cataclysm that doesn't hit lands is no cataclysm. Plus it's kinda easy to see coming out of the CZ so people can play around it. The 0 is completely bonkers for a 2-drop, so that's where I'd consider the bread-and-butter value of the card, but tbf in commander it's not likely to be game-winning or anything. If you have so many creatures that it IS game-winning, I think you could have just gone to combat to win instead. More often I think it's annoying as a repeatable creature removal, which is strong but in 4p not game-winning. So I think overall it's strong, but unlikely to just run away with a game.

Tamiyo is honestly pretty strong on the front side. Just make clues all day seems fine. Flipping is pretty easy - Brainstorm does it immediately, or you can just crack 2 clues on 4. +2 is good for keeping her alive but, in commander, not super impactful. -3 is...well. time magic exists and ruins everything so...bleh. Ult is pretty win-the-game-ish. Overall she's probably the strongest, even if her + isn't all that great. Her front side is very strong, flips for doing something you wanted to do anyway, and her - and ult both have game-winning potential.

Sorin seems comparatively fair. Front side is pretty weak so you probably want to flip. + is pretty crap. ult is surprisingly weak. - seems like the main value. Use a bunch of lifegain and then nuke someone. Of course we already have Vito, Thorn of the Dusk Rose, who can go infinite, but Sorin adds white which is a big advantage. I'm sure it'll see play but it's not crazy scary.

Ral is weird because he's almost better on the front side. His + is just continuing to have that ability. His - is underwhelming for commander but at least it gives you a card in a pinch (though spellslinger might have the hardest time with the color requirement). Ult is...fine...I mean, it could win the game, but the most reliable way to flip him seems like it'd be casting a bunch of cheap cantrips and flipping him, but then you probably hit a bunch of air off the ult. And since his + is a +1 and his ult is a -8, good luck getting there if you flip him with 3 counters. Seems like a pretty vanilla spellslinger commander. One interesting note - when you go to flip him, if you're going to cast a bunch of spells that turn, cast your sorceries first and decline to flip, then hold priority and cast all your instants in response to casting your last sorcery. That way you'll get a counter for every spell, without the risk (or at least, a much smaller risk) that you'll whiff and miss the flip after declining earlier in the turn (when you'd cast fewer spells).

Grist is probably my favorite. The front half looks like a reasonable magic card instead of insane MH nonsense. Flipping him takes a reasonable amount of effort. Back half is pretty neat. His + is strong but fair, the dt counter is unreliable - guess you want a black-heavy build. - is good utility. ult is strong but definitely needs some setup, which I definitely prefer to "just win the game" ults like Tamiyo. Probably the one I'm most likely to build.

Flip Grist is even better than OG Grist for Zask, Skittering Swarmlord. I wasn't really planning on that deck becoming a staple, but I keep finding new cards and new cpoilers I want to add to it, which is the sign of a deck with longevity, so we'll see.

As for playing them in the CZ, I think not-tribal Ajani is pretty strong honestly, just +0 every turn to build your board while keeping your opponents down. Win with Goblin Bombardment or get enough cat tokens that the +1 becomes a problem.

Tamiyo might be better, but it's Simic YAWN

Sorin is really weak, but he's Extort in the CZ, which I believe is new? Extort has always played way better than it read, so honestly, getting it on a 2 drop in the CZ alone might be worth brewing

Ral is both bad and Izzet, DOUBLE YAWN

Grist might be ok in the CZ. I do like the idea of having a guaranteed t1 play every game.

Someone at WotC heard my perpetual complaint about no Godsire reprint and decided to taunt me with Ulamog's Dreadsire. 10/10 vigilance ward for 10 that taps to make 10/10s? Seems hilarious, but it can't be hit off Bag of Tricks or Natural Order D:

A Island version of Magus of the Moon

That Goyf-matters legendary has a wacky ability, and it even makes Tarmogoyf tokens!

(Yes the other four medallians are here too.)
