Also, weird question: are we allowed contraptions?

Also, weird question: are we allowed contraptions?

From the rules of the game when it was posted:

- Any card can be named, regardless of legality.

I would say that means yes to contraptions.

Sol Ring

[ApothecaryGeist]

Graven Cairns

[WWolfe]

Polluted Delta

[Morganator 2.0]

We have 19 cards and 8 lands. I'm not sure if I'm going to do my contraption idea, because we would need a minimum of 15 contraptions. Instead I'll do Nullstone Gargoyle for today.

Sorry for the late response, I've been busy lately.

As for contraptions, I know I said all cards are legal, but since contraptions don't go into a separate deck, I'm gonna have to say no to them.
Otherwise, things could escalate, adding in schemes, conspiracy's, ect.
If we allow things outside of the 99, this might never end.
Sorry.

Aside from the one typo - thins should be this - I think it is how it was meant. 
+ represents the word 'positive'.

Correct. Also, this is why you proof read, kids.

Today, I'm going to go with the Best "Tri" land for this deck ... Mishra's Workshop
