MTG Salvation

I'm imagining this with Ral, Storm Conduit. I'm pretty sure that kills them with just a Shock.

Lets see. Kefnet cast, your next cast x3. Downtick ral, get an extra copy. Play it. Four instances of your next cast spell tripling. If they can see and affect each other, just casting it twice goes infinite, if not, the next spell you cast, you cast 9 times total, with 11 copy triggers between your second cast of it and the subsequent spell copies, at which point they'd probably die even to just a lava dart

God-Eternal Kefnet reveals Repeated Reverberation. You have Ral, Storm Conduit on the field. you have 7 lands after playing one, and a shock. How much damage is that?

Kefnet gets a discounted RR. Next you go to main, activate Ral, and cast RR. Your earlier RR from Kefnet copies this twice and Ral copies it again. So now you have 4 RR triggers waiting to go. You cast shock, it gets copied 8 times, and you do 18 damage.

Did I do those triggers right?

The good news is most "I win" ults aren't that much more effective when tripled.

You start out with the assumption that ultimates are more than gravy.

I'm not saying a double-fork is weak. My comment was that if you're going to be hit with a Teferi emblem you'll get met with the same instant concede weather it resolves once or three times. Or if you're hit with Liliana, Dreadhorde General's ult the duplication doesn't do anything. Its some comfort to consider that the strongest effects that can be duplicated aren't the best strategic uses of this card.

The bad news is, things like Goblin Grenade are.

This is the worst wording ever. I had to rephrase it to readable English: "The next time you cast an instant or sorcery spell or activate ..."
