i like the forgemaster deck a lot. but it runs four jaces...

i might look into getting a few of them but...what do you think of diabolic tutor instead for the time being? jaces primary reason for being in the deck is his 0 ability, digging for a forgemaster usually (i know he does much more but thats the MAIN reason...). and the tutor occupies the same spot on the mana curve and is much more effective than the brainstorm.

just some thoughts! what do you think?

Good thinking on the tutor. You want to hit the kill condition that well do it. Its just you now advertise, i got my kill condition answer it. At least with jace there is a suprise factor plus an alter win condition. I do like the tutor. Try it out or just try more draw power to keep your hand flooded so you have answers for your cards to come out.
