(Updated, unsatisfactorily, for post-rotation)

I really only built this to test if Riptide Chimera could be used similarly to Roaring Primadox . There aren't as many cheap ETB effects right now, but it's got a mix of Constellation, Heroic, and Bestow to maximize the utility and synergy. It's gimmicky as fuck, but it's fun to play.

When you read this, keep in mind how each card might work well with Riptide Chimera . That said, it's a decent deck even if you don't draw Riptide.

I don't have many answers to enchantments, artifacts, and hexproof. I'm pretty sure all this bouncing back and forth would be terrible against control aside from hopefully running them out of cards most of the time and possibly aggroing enough.

1 Drop

Hypnotic Siren - Most decks don't have much for early flyers, so you should get away with a few damage from her.

2 Drop

Spiteful Returned - Generally 2 damage no matter what. One game, they didn't have a blocker for 2 turns so they were down 6 early. Cheap enough Bestow cost for what it is.

Brain Maggot - I almost included Despise , but the fact it's an enchantment creature helps Constellation. I had two occasions where all they had was land, but at least I saw their hand, and unlike Duress/Thoughtseize/Despise, now I had a chump blocker. With Riptide Chimera in play, this card could get tedious for a few turns. You'd usually want to bounce Brain Maggot on your upkeep and play it again right away. You could view their hand each turn for 2 mana if you got that combo going, plus be able to switch what you want to exile if they draw something better. Against blue, you'd have to pay attention to whether they're tapped out, though.

Fate Foretold - Draw engine, might prevent them from trying to kill something.

Flitterstep Eidolon - Something to replay with Chimera. Could do some damage with a Spiteful Returned.

3 Drop

Dissolve/Hero's Downfall - Control. I don't have a lot of it, but so far it's bailed me out of some sticky situations.

Grim Guardian - His Constellation ability isn't that impressive, but it's the earliest Constellation in these colors. Being 1/4 he's resistant to things like Anger of the Gods and Bile Blight, as well as being a solid blocker.

Riptide Chimera - Makes everything in this deck better. Except for other Riptides, actually. There's no reason to play two of them, but then again, holding one in hand forces you to be patient. 3/4 flyer is good as-is. Sometimes if it's your only creature, you end up playing him as a blocker every turn, but it also kinda gives you options to wait to play him until you put out a couple other enchantments in the right order.

4 Drop

Doomwake Giant - Kill weenies.

6 Drop

Thoughtrender Lamia - Mostly a finisher, but so far every time I've played her, she's been killed immediately. Also good against any sort of control.

Extinguish All Hope - Running all enchantment creatures, why wouldn't I?
