Unwelcome Thoughts (1UB)

Sorcery

Target player sends the top two cards of their deck to the graveyard, then discards one card.

What? No! Why would I ever do that to my sister?!

Brain Bleach 4UUU

"Well thank you for that thought. Now I have to go clean it out of my brain. Violently."

Ooo! Shiny! 2RU

No, I'm not distracted, I'm merely OH HEY WHAT'S THAT!?

Can you play cards in your draw step? If not I think this card would just mean "do nothing but slowly mill your deck for the rest of the game".

edited 12th May '15 11:09:08 AM by Elfive

I would assume so, if they're instant speed.

Which reminds me, I should probably have added "as if it has flash" in there somewhere.

20/20 Hindsight - UU
Enchantment
Each player skips his or her draw step.
During each player's end step, that player draws two cards.
Wait, I could've - dammit!

You absolutely can play cards in the draw step. That's why instant speed discard is so powerful.

It's also done in Standard. You can kill a Courser of Kruphix to stop them from playing the top card of their library and to see what they'll draw next turn.

@Imp: An aura can enchant a player. See Curse of the Bloody Tome and other stuff with which I'm not as well acquainted.

Called Away (2G)
Enchantment
When ~ enters the battlefield, search your library for up to three nonbasic lands and exile them.
~ enters the battlefield with three charge counters on it.

Skip your next turn

Ancestral Desecration - BB

Target player discards three cards.
Forget the ways of the past. Our ancestors are nothing but bones and dust.

Tony Stark RU

Legendary Creature - Human Artificer

{T}: Equip target Equipment artifact.

2/2

Iron Man 6

Legendary Artifact - Equipment

Equiped creature gets +6/+6, Flying and Hexproof.

Equip 6

6:Iron Man becomes a 6/6 colorless artifact creature with Flying and Hexproof until end of turn.

I need to get this off my mind, enjoy. I'm iffy about hexproof and wording in general. Something feels off. And i forgot how to post, apparently.

YES! Flying. Facepalm. Edit.

This was going to be a sort of reply to , but I kinda lost that by the time I got to the flavor text.

Awaken the Tombs 3BB
Sorcery
Exile any number of creature cards from any number of graveyards. Put a 1/1 black Skeleton creature token onto the battlefield for each card exiled this way.
Sticks and stones, rather famously, can break your bones, but the three put together can break anything with enough effort.

You forgot to give it flying. And maybe it should have first strike or firebreathing or something.
EDIT: Also, Tony should probably be a 1/1 or something; the guy doesn't seem like that great a fighter outside the suit, and I don't think he even bothers to carry a weapon.

I'm biased against 1/1 creatures.

One of my favorite things to be able to do is get a Hopeful Eidolon out on turn 1, slap Ethereal Armor on it, and swing with a 3/3 with first strike and lifelink made out of commons on turn 2. Hell, one of the first moments I had in the game was when I realized Ethereal Armor stacked with itself.

If you get really lucky, you can get two Armors on it, and swing with a 7/7 instead.
