@Wurms, what's the point(s) of this card?

How I'm reading this is it's 2 mana to flash-bounce a nonland permanent (seems a bit weak, maybe, but definitely not strong). However, you have the choice to discard up to three cards to this those many more times... I mean, why though? Why would you want to pay 2 mana and discard 3 cards to bounce 4 permanents?

Why would you want to pay 2 mana and discard a card to bounce 2?

TBH, this seems like the card you'd play out of pure desperation... However, I find it hard to believe you're going to have three other cards in hand and toss them all just to save your life, when they might be helpful themselves

This just seems to be a bit weird to me, unless i'm missing something. Maybe keep the three instances thingie and redo this card? Idk what this is good for, also, the flavor is alright, but not great. Especially for the focal points of Kragstorm's Eternal Storm.

Honestly, you could make this a Legendary instant/sorcery and just call it The Eternal Storm. Or maybe save that name for a Saga you might want to make. But this would be a good choice for a legendary instant.

Honestly, my main problem with this is that it's kind of a boring card for rare, and it's also not very impactful.

I was trying to make a hellstorm card with a powerful control effect. this was heavily inspired by Cyclonic Rift and serves the same function. It seems like one of the better hellstorm cards in the set. Note that Cyclonic Rift is one of the most played cards in EDH. No doubt this is weaker, but with hellstorm synergies it can pull of some crazy swings. I was actually going to nerf it yesterday to just have hellstorm twice. Mass bounce is really strong in pretty much any format but insane in multiplayer. I made this thinking it would be the 'face card' for the mechanic. Meaning it is viable in competitive. I trust you to balance the effect if you want. As for the flavor, it seems pretty spot on to me. A storm's eye would definitely act like a hurricane and throw stuff everywhere. Just some thoughts. The legendary idea is cool, but I can't see it working on a cheap card like this.

"A storm's eye would definitely act like a hurricane and throw stuff everywhere"

Yeah that's actually pretty good flavor, I either missed that or forgot to mention it.

The thing about Cyclonic Rift (not that I've played with it) is it's way stronger. Viashino Storm-Wielder, Storm's Eye Seeker and Thunderfish are the only cards that care about Hellstorm. Doesn't seem like enough synergy to make this equal in strength, except in an ideal situation (one of each on board, maybe even multiple copies in play for any of them)

Honestly, the flavor is fine, the mechanic is okay... My main gripe with this is that you're discarding 3 cards and paying 2 to bounce 4 nonlands

compared to the rift which is 7 mana to bounce everything. I'd much rather wait until my turn 7 comes naturally to bounce a board then to discard most my cards early-game to stall an opponent as much as I'm stalling myself. Sure, if I have Storm Wielder out, I get to bolt them once (hopefully all) their stuff is gone, but IMO, there's never a good time to activate this more than once. Discarding a card for an extra bounce is questionable but might sometimes be the right choice, but that would fit a Common more than a Rare.

Honestly, by the time your opponent has 4 threats on board, you're not gonna have three cards in hand. Even if this archetype had better card advantage (it has some, but not lots, especially since it ranges from aggro to aggro-control to tempo, from first look no playtesting) but not enough for something like this to be viable.

Honestly, I like this card a lot, I'm just worried it's too weak. I suppose having a dead card in hand isn't awful for this archetype, since what else would you rather sacrifice to the storm?

A (less interesting, stronger, probably common-not-rare) idea for this card might be:

Return target nonland permanent to it's owners hand. When you discard this card, return target nonland permanent to it's owners hand. Could maybe be uncommon, too. But might as well be common.
