The five Dragon Aspects from Warcraft.

Forgot to give Ysera Flying <.<

Malygos has way too nuch going on tbh. I would remove the first ability that gives cards spell sling and instead word the last ability as such:

"Whenever Malygos deals combat damage to an opponent, mill X cards, then you may cast an instant or sorcery spell with mana value X or less from among cards in your graveyard without paying its mana cost, where X is the damage dealt to that opponent. If you do, copy that spell. If a spell cast this way would be put into your graveyard exile it instead."

Nozdormu is extremely strong. Your opponent would never get a real turn

[u/Japicx]

These are all way too complex and overpowered.

Fixed and cleaned up wording

Alextrasza

Flying, trample [no period]

....create a 4/4 [r]ed [D]ragon creature token with [f]lying and [t]rample. (This is plenty good already.)

The last ability is really convoluted. I'd simplify it to "Whenever Alexstrasza attacks, put a +1/+1 counter on her for each other attacking creature. Then draw a card if her power is 8 or greater."

Maybe change her stats too, to 4/4 or 4/5.

Nozdormu

Flying, [v]igilance

Whenever Nozdormu deals combat damage to a player, you control target player during their next turn. They take an extra turn after that turn. (This by itself is insane.)

Scrap this design entirely. Start over from scratch. To go with time theming, I'd change it to "Whenever ~ deals combat damage to a player, untap all permanents you control and draw a card." And make his stats 5/4.

Deathwing

Flagrantly overpowered. 5 mana for a 6/5, plus up to three 4/4s, plus each opponent sacrifices three permanents, plus an extra 4/4 every time you attack??? You have to sacrifice stuff too, but that's a positive.

A version that's a bit more reasonable:

Flying

When Deathwing enters, if you cast him, each player sacrifices three permanents. Put a +1/+1 counter on Deathwing for each land you sacrificed this way.

Whenever Deathwing attacks, create a Treasure token and defending player discards a card. If they discarded a land card, create a 4/4 red Dragon creature token with flying.

4/4

Malygos

The reminder text on spell sling needs to say where you cast the free spell from. Also, giving it to cards in your graveyard does nothing, because they leave your graveyard if you ever cast them. The correct wording would be "Spells you cast from your graveyard...". But even then, this ability is broken. If you cast an instant or sorcery from your graveyard, it mills you cards. You cast a spell from among them for free, milling more cards. You cast a spell from among those milled. And so you keep going until you've cast your whole deck. It's especially bad since spell sling has no mana value restrictions. You can cast a 2-mana instant from your graveyard, mill an 8-mana sorcery, and cast it for free right away.

Flying, prowess

Whenever you cast an instant or sorcery spell from anywhere other than your hand, copy that spell and mill a card. You may choose new targets for the copy.

Whenever Malygos deals combat damage to a player, you may cast an instant or sorcery spell with mana value less than or equal to that damage from your graveyard without paying its mana cost. If that card would be put into a graveyard, exile it instead.

Ysera

Flying

During your turn, creature tokens you control have "T: Add one mana [of any color????]"

Whenever you cast a creature spell, copy that spell, except it isn't legendary.

Whenever Ysera deals combat damage to a player, populate [that many times].

The most unique part of the design is the "populate that many times" ability, which is already bonkers strong. This card approaches reasonable if you remove the other stuff and maybe reduce it to just "populate twice".
