Why no Vexing Devil?

Because you never will get the option you want, and it sucks after turn 1.

having a 4/3 is almost, if not as, good as dealing four damage. think about it, if your playing control having a one drop 4/3 can be devastating to them.

Deckmonster99 was an asshole

Vexing Devil is aite, but its been replaced by other better cards. For example, 8 Skullcrack's.

Control is non-existent in the meta. And as an important rule in magic, never play cards that give your opponent a choice. That choice will always be your least favourable.

What happens if you topdeck devil when they are at 3?

You lose.

well not really lose but...

And yeah, deckmonster was an ass.

I think that 3x Sacred Foundry would be better only because Kor Firewalker costs double white. Say you get a Molten Rain to one in the mirror. Suddenly, you're praying for a Lightning Helix and if it doesn't come up it's likely that you lose. I just think that the firewalker is too important in the mirror and it's not worth the risk of losing him so easily.
