Rules Q&A

Corrosion

Enchantment

Cumulative upkeep (1)

At the beginning of your upkeep, put a rust counter on each artifact target opponent controls. Then destroy each artifact with converted mana cost less than or equal to the number of rust counters on it. Artifacts destroyed this way can't be regenerated.

When Corrosion leaves the battlefield, remove all rust counters from all permanents.

I thought Corrosion was a pretty solid answer to this...

I’m sort of surprised Heat Stroke isn’t used more. I know it’s too slow for red burn, but I would assume token decks would get value from it (my goblin deck certainly does). Artificer's Hex is an all-time favorite of mine for my haunted house deck. Equipment cards bug me almost as much as planeswalkers so I love messing with them. It’s strong because it doesn’t outright destroy it, so GY recursion doesn’t save it. It’s weak (but more fair) because the player can still choose to use it if it’s worth the creature dying, which makes the play more engaging. Similar to equipment, other artifacts are so core to Standard EDH Decks(tm) that something like Corrosion can jack up a 4-player game big time. Clearly, I get a great deal of enjoyment out of dragging other players back to 1996 by destroying their insane swords and 1/3 flying first strike 1cmc creatures (or whatever). Giant Oyster is far from flashy, but killing things (even fliers!) with -1 toughness is strong, and especially brutal if they have to watch it happen over five non-untapping turns. (Note: sorry if you’ve looked at my decks before, I’m obviously just scrolling through them at this point) Walking Sponge can sometimes make wild swings in momentum in multiplayer. Hilarious. Homarid Spawning Bed produces so many tokens that I’m certain that if I was better at making functional decks I could misuse that in some sort of sac-outlet jank. How do you get giant creatures into play that are worth sacrificing? Glad you asked! Iceberg is such a crazy amount of ramp for blue I’m astonished that it’s not more popular. My guess would be that it’s practically impossible to find, because blue always wants blue mana rather than colorless and because cool new blue stuff is basically free anyways ;p but I've loved it ever since I found a (one!) copy of it for my Briny Deep deck. Breaking Wave might be something The Cool Kids are still using (sadly I wouldn’t know) but if it isn’t it absolutely should be as it can be bonkers. Paralyze was a lot of fun to use on your own creature that wouldn’t otherwise untap in your untap phase. I hope that still works nowadays. Transmutation had always been fun, and I hope it’s still useful. If you enjoy making deals cast a Callous Oppressor and start the bidding high! Do you like hurling insults down at the two strangers fighting in the ring? Get yourself a Whipkeeper and turn it up to eleven! This is way too long a post, so I’ll stop and see what else comes up in the posts. I’m looking forward to hearing about other people’s favorites!!

My decks are terminally bad (but themely!) so my contributions will be limited in value, but here are some of my favorites: Transmutation Encrust Artificer's Hex Iceberg Rain of Gore Corrosion Heat Stroke Harsh Mentor

There are some hilarious cards out there if you want some jankiness.
Archery Training for some pro sniping.
Armageddon Clock if you just wanna watch the world burn.
Armor Thrull because +1/+2 is better than +1/+1.
Azor's Elocutors...win the game? ok.
Clockwork Avian or any other clockwork dudes are funny.
Corrosion to kill all the pesky artifacts.
Djinn of Wishes is lulzy if you want more than just 3 wishes. Yes, you can wish for more wishes now.
Endless Scream because errata.
Essence Flare for a slow death.
Fylgja idk this name is just worth it.
Greater Werewolf and other oldschool werewolves have hilarious effects.
Lead-Belly Chimera and other chimera like +2/+2 counters.

There are some other goofy ways to use proliferate that are actually pretty decent.

Like getting an extra level on the level-up creatures.
Or pumping your slimes faster with Gutter Grime.
Or just ramping like a troll with Hickory Woodlot, Iceberg, or City of Shadows.

All in good fun.
