Uh oh. I can't see you casting this and not immediately winning

Well; you're not likely to cast it until you've gto some combo that can untap all your artifacts for less mana than they're making you.

But I don't see a problem with this; I mean, High Tide is a thing.

Actually; I do see one problem - I'm not going to want to see this in a pack in draft. It's unlikely even to pay for itself. So it should probably be rare, if only to free up a slot; unless this set has more artifacts than Mirrodin. (It doesn't.)

­High Tide is a thing of the past. It's about as much a thing as Prodigal Sorcerer is a thing. It's a thing that since has moved to red.

Mmm, yeah; true. Blue gets to reduce costs; red gets to make bursts of mana.

Blue gets to reduce costs, but plenty of artifacts generate mana. If this ability appeared on a colored card, what color do you think it would be?

As SI says; a red card "As an additional cost, tap X cartifacts you control; Gain X red mana" would be well within Reds remit.

Turning all artifacts into islands for a turn would be green :)

And blue could write "Artifacts gain: : Reduce the cost of the next spell or ability by " :)

The colour stretch here is fine-ish. I'm more wondering about dude's power level comment. Because I'm really not seeing the danger here. Is it just that this card is just "99% of the time complete junk, and in 1% of decks the key to infinite mana", and so should probably be a rare?

I'm unsure if Dude is concluding that this card is broken. He isn't wrong that when you resolve a card like this, you tend to win. Of course, a card like this tends to sit in your hand if it doesn't win you the game.

To be honest, it seems balanced to me. What's the best case scenario in 'Arena Standard'? You put out a bunch of treasure tokens and can now activate them for colored mana instead of sacrificing them? Seems... kind of tame.

Most of the time the problem with fast mana is that it lets you jump over the early or mid game and head straight to the finishing blow. But this card asks you to develop first, then asks you to tap out everything you developed to go big on it. Granted, if you're playing affinity and can dump a whole hand full of artifacts on the table by round 2, then this starts to get crazy dangerous. But Affinity was already a broken mechanic, and having access to a lot of Blue mana in that deck only encourages you to add cards that will make the Affinity deck weaker.

But, yeah @Vitenka, comparisons to High Tide is probably what got Dude to respond the way he did in the first place. High Tide is an unfair card. It lets you combo out to victory in the mid-game with the only restriction being "play a bunch of Islands like most Blue control decks do anyway."

Yeah, this is just High Tide for Modern storm and cheerios decks. That's what I'm scared of. Plus it's even easier to untap artifacts, so this can also go infinite pretty trivially in larger formats. Standard could be built around it, but that will also have a minor warping effect that's probably not worth it

Ooh. Untapping artifacts was not on my radar. While I never want to see a broken environment, I would love to see the eureka day when a developer finally breaks a card.

Considering Paradox Engine gets you killed on sight in my meta, it wasn't a very hard stretch

Well yes; that's a very powerful card. And one that enables huge combo's.

This is also a combo piece. I don't see a problem with that. Maybe development would end up tweaking it to cost more or something, to stop it going off too soon - but needing at least three artifacts to be able to get this going at all seems like a big enough barrier that this won't be complete cheese.

Strong? In the right deck; sure.

I like being able to stop your opponents combo for a turn with this

Fun!
