Disclaimer: This is entirely copy and pasted AKA netdecked. Sideboard is important because of Wish, Stroke is the only instant speed kill I think.

I so want to play this. Firstly it's legacy, so it'll work forever (maybe not top-tier, but still powerful). Secondly everything barring the lands and Force are pretty cheap. Force is kind of optional for non-competitive too.

It's also my style, sit around and draw cards for a while. Then combo into a Brain Freeze for 60. Plus, everything is instant speed, so you can always wait until the very last possible moment before attempting to go off. As in you can win the game in response to someone attacking you to death with damage on the stack. In fact, Reset encourages this kind of playing.
