I would love feedback on this card, as the numbers I placed on it are kind of arbitrary and random

I would put the life gain first - it might be weird for players to handle going to negative life during the resolution of a spell.

So... this is for "You gain 15 life." That's not kosher.

The life gain of black is usually tied to destroying something in turn, so "Each opponent loses 1 life, you gain 1 life." would be a more fitting mode.

Note that a target must be legal as you cast the spell and choose targets. Maybe you intent the second and third mode to be a combo? In that case you want the third mode to change to "Destroy target creature if it is tapped. You lose 3 life."

I could also see this progressively trading up resources e. g.

Choose five. You may choose the same mode more than once.

• Each opponent loses 1 life. You gain 1 life.
• Draw a card. You lose 1 life.
• Discard a card. If you do, create a 2/2 Zombie creature token.
• Each player sacrifices a creature.

Heck, you could go for "Choose X." that way.

... For future reference: Display of Power.

Yeah; gaining 15 life is a very odd thing for a black card to be able to do.

How about losing that last entry, and instead having wording like "You can prevent the life loss, that counts as an extra pick"?

There is going to be a lot of confusion about the last ability not going to be able to target something you tap with the third ability.

This can still be used in pure life-gain mode; which seems wrong. Why not just ditch that first mode?

Valud point. Alternatively to ditching the mode you can replace it with a drain effect. At five uses that's Stolen Grain though which is above curve...

Alternatively, black could trade something nominal life. "Exile a card in your graveyard. If you do, gain 2 life." might be more palatable to the color pie lawyers.

By the way, I like where this card's head is at. My inner Melvin is screaming, though, that this says "Choose 5" and there are only 4 options. I know that's the point; that you're supposed to choose some things more than once... but it just doesn't feel right that you can never choose one of each.

Personally, I would drop this to "Choose 4" with 4 options, of which you can choose the same one(s) multiple times. But that's just me, I suppose.

It'd also be nice to have a 1,2,3,4 progression. Currently you have +2/-2/-2/-3. But that's SUCH a minor point.

The last two items go together - tap, then destroy if tapped. That's pleasing. It'd be nice to somehow make all of them work together in such a cascade.

What do you do with the number 5?
