my main priority is to make it fun. i have 67 unhinged unglued cards which includes 5 cheatyfaces. many of the un cards plus other fun or lower theat cards i have changed to 0 mana. lands, 0-cost-cards, and cards that are being paid for in a way other than their mana cost (bringers, traps with conditions met) do not count for your spell for the turn, and you draw a card when you play one. since the deck is so big, i had to resort to adding counterspells similar to mana leak, whereas the spells controller would not be allowed to pay the mana. this way, there is more balance since there are more counters. additionally, my friends and i have created 10 of our own planeswalkers of each other to up the fun factor even more. suggestions are welcome but i mainly posted this to help my friend get ideas
