Commander Game

{Akai Ryu}Whoa, this is a strange card. It has a huge color density (wanting two mana of three different colors), but then they only want it from basic lands which makes mana fixing for those cost really hard. And then there is that activated ability that tells you to play a lot of forests (which should be capitalized in the text box by the way), which is again harder if you want mostly basic lands and not duals. The Nymphs definitely want to play Prismatic Omen and similar to fulfill all those requirements. At first I also thought this would be a nice synergy with ‌Suppression Field, but then I realized that with the untap you get the same result.
I think it's very hard to really make this card work, but if you manage to do and have enough forests, the Nymphs are going to be pretty deadly pretty fast. And I don't think paying two mana repeadedly to shoot your opponent in the face for a bunch of damage is a fun way to win.

{kinotherapy}A strong card and a really nice Fearie tribal commander. I guess she also likes to play cards like Underworld Dreams and Megrim. I can't tell how easy the token creating gets our of hand, but I guess you'll usually get quite a bunch of tokens and thus draw quite the ammount of hate.
The art looks like a mixture of Oona and an Ixalan merfolk XD

{notfoxwolf}Personally I don't like landwalk abilities. Also Wizards stopped doing them, because they are a weird kind of color hate (and they are doing very few color hate in general nowadays).
I like the other two abilities and how they interact with each other without necessarily needing each other to work. Since Kata costs hybrid cost, it means the card has to work both as monoblue and monoblack. I think it's ok since what he (she?) does is more of a bend than a color pie break.

{oddnanref}If you'd give Miran also an extra attack on his (her?) trigger, he'd be more expensive. This way he's a nice and cheap go wide commander that also really works in monowhite. Since he doesn't give you an extra combat step, why does he only trigger on the first attack? Even if you'd get some extra combat step, triggering his ability another time wouldn't be overpowered or something. I think you could just word it like battalion.
Adn I think you mean to grant +1/+1 and first strike until end of turn?

{Casstastrophe}Annihilus is a real powerhouse. I see two problems with him: First the tecnical one: If you put that text on a magic card, the text gets quite small.
The other thing is that he grants six abilities at different times to different creatures. I know if I played against him (or maybe even with him), I'd had to ask my oponent every second turn which of his creatures get what abilities.
The card itself is not really a problem, but it just has too much going on at once.

{amechra}I really like the first ability. It can be really powerful but has this classic red chaos factor. Are you going to draw two lands? I guess the ability is really great if you want things like threshold, delirium, flashback and other graveyard machanics. Maybe it's even a bit too powerful, I don't know.
I think the additional discard to draw isn't needed at all. Also It seems a bit redundant in face of the first ability.

{4d20}Counts. I just don't know why you'd ever pay more than on it. It's a mono-white commander. And she has already three white mana in her cost. I like the card overall, it's good but not overpowered. I just think the twobrid is unnecessary. I think twobrid in that place would make a lot more sense if she had another color than the activation cost.

{fluffyDeathbringer}It's a good and simple hatebear. I just don't see why I would play her (him?) as a commander. It's very meta-dependent if this would be good and I don't see any build-around potential for her.

{wuzzle}Kalumina looks like a fun and interesting card and a nice build-around. The only thing I'm unhappy with is the last sentence. Permanents themselves don't cause abilities to trigger. It's the permanent leaving or entering the battlefield that may cause abilities to trigger. Another kind of weird formulation I can come up with is "Then, if no triggered abilities are waiting to be put on the stack, draw a card."

{winner}kinotherapy wins. Second place goes to wuzzle
