WHY THE 4 Transguild Promenade

Sorry I've just noticed that I hadn't explained that in the description, and I've just updated accordingly. It's to allow you to use the abilities from stolen monsters as you can pool any colour from them.

Why cancel? You can use Dissipate . And by the way, you can give yourself +1. +1.

That's a really good idea, thanks Scorprix. I don't actually own any of those so I shall put them on to my to get list.

I would consider the new Dissolve over Cancel, since it's the same thing but let's you scry, which is always good.

Yeah in this deck that would be really useful ... I could swap Dream Fracture and Cancel for Dissipate and Dissolve then. Or keep Dream Fracture ? What do you reckon?

Swap it. Card advantage might be good, but there should be better ways to do it. I don't play blue, so I don't know them off the top of my head, but Im sure they exist

Good point and giving your opponent cards isn't necessarily a good idea unless you specifically want them to have them and that doesn't really fit with the deck's theme.

I'm considering swapping Deprive from the sideboard into the main deck as Deprive + Roil Elemental is a very useful combination. By the time you have the mana to play Roil Elemental it shouldn't matter too much if you're picking lands back up as you should be able to afford to play virtually anything else in the deck. This gives you a good flow of lands to allow you to keep using roil elemental's ability.

If I do this I'm going to have to swap something into the sideboard and I'm not sure what to choose, any ideas?
