The Golden Game

Not entirely sure this needed to be Bant, the abilities and flavor fit perfectly well in W alone. I can see WU, but G is very much a stretch. While no defender means you can beat in with it, 5cmc is quite high- I’d try 3. The ability at 3 is probably a good choice (although 2W is a better fit). I like the versatility of the activated ability, since it’s most useful for blocking (as you get two blockers), pretty useful for attacking, and even has a niche use against burn.
(also- human cleric, I assume?)

The statline feels quite above-rate for something that dodges removal- I’d put it at a 3/3, or at most a 4/3. Also not a big fan of the trigger occurring on not only exile removal but also tuck/bounce. I like the overall flavor, especially since it justifies the presence of other Fish in the set- something necessary to make the card useful at a limited level (gatecrash was the only one in recent memory to have more than one due to Simic shenanigans).

The top end on this is certainly high, as this provides an immediate two points of power if you landed a two drop while also being able to swing in as a 4/5 by itself. The token being a separate body is quite relevant as well. This would be less swingy either at four mana (and maybe 3/3) or dropping the exalted from the Rhino body.

Haste tribal, eh? In limited this will have few targets at common- often only one- making this very rarely worth the deck slot. This as an aggro topper in constructed could be interesting but also drastically restricts your deckbuilding. I do like the interaction with group pumps even if it is less intuitive with the flavor. My first thought upon seeing this was how it would throw creatures- imo adding an ability to grant another creature haste would heighten the flavor and make it more useful in limited.
(also minor wording- “creatures you control with haste get...”)

Interesting for limited (likely too fragile/slow for constructed). Fulfilling the condition doesn’t leave you with much in terms of blockers, but the high stats pushes you towards aggro anyway. The challenge for a X/2 is making sure it results in something useful when it swings in, and menace and trample means not only can it kill small fries but push through a bit of damage as well. The payoff of a 5/2 is quite potent with that ability set- perhaps a bit too potent. A 2/2 that ends up as a 4/2 might be a better spot.

This isn’t a creature and is thus invalid- sorry! If I had realized earlier than while I’m typing this judging I would have posted in the thread about it.
Comments anyway: Took me a second to process when this would actually be cast. The power level is pretty low, seeing as you have to hold mana up, it’s telegraphed, a condition has to be fulfilled to get the full effect, and it’s a multicolored card in a space where Titanic Growth and Larger Than Life exist. Overwatch is a neat mechanic but I don’t think this effect is a good fit for it.
(wording- think it should be “the beginning of your next combat, ...”)

Is this how the spoilers work?

Acuindra seems quite powerful. If you have the red creature, it’s often 4 mana to hit for 4 and kill a creature, and even without the first strike it still hits hard. Uncommon seems right, and I don’t want to play against two of these at once. I don’t get why it specifically checks for red creatures, but overall it’s a great design.

Menace on a Ball Lightning variant is very interesting, and Unearthing this late-game can win you the game out of nowhere. Technically mono-red can do all these parts (at least in a setting like Grixis), but as a whole the is necessary. Nicely done.

Very interesting design, but I think it’s too powerful. Instead of surveilling as you intended, people will use cards like Arc Slogger, Cadaverous Bloom, Demonic Consultation, or Crook of Condemnation to generate massive value with Duskmantle Reborn. There’s a reason why anything that’s exiled is permanently gone.

This ability doesn’t have to be modal. You can just say “exile target spell or creature”. I’m not sure if White is supposed to exile creatures (permanently) for 4, but I’ll allow it since it’s hard to cast. It reminds me of Venser, Dhaper Savant. Very clean design.

This is a major blowout. 6 mana for a 9/9 with trample, that removes 2 permanents, at instant speed, is a bit much. Even if it gets killed right away, it’s still just trading for a card, and it’s absolutely absurd when it doesn’t.

ZephyrPhantom! Congrats!

Whenever a non-Horror creature enters the battlefield under your control, destroy it.
For each creature destroyed by any of ~'s abilities, create a token that is a copy of the destroyed creature under your control. It's a black Horror in addition to its other types.


Edited: some text and higher mana cost. Might still be too low. Hope I'm not too late 

{old}Here's an old version of the card's text as well:

When ~ enters the battlefield, destroy all non-Horror creatures you control.
Whenever a non-Horror creature enters the battlefield under your control, destroy it.
Whenever ~ destroys a creature, create a token that is a copy of that creature. It's a black Horror in addition to its other types.



And an even older version:

When ~ enters the battlefield, destroy all non-Horror creatures you control, then create tokens that are copies of the creatures destroyed this way. They're Horrors in addition to their other types.
Whenever a non-Horror creature enters the battlefield under your control, destroy it, then create a token that is a copy of that creature. It's a Horror in addition to its other types.
