To further the cause of tempo...
What players are looking for is The Golden Ratio.
Cards that deliver the correct amout of power at the right time for the right price.
We want Shivan back because 6 for a 5/5,F,fb is NOT overpowered.
We want Juzam back because 2+Ritual for 5/5,-1pt is overpowered, but balanced since if paci'd or stopped by a regen, it still pings every turn. The price of gambling with a fast critter.
When WotC makes a fast set, it's fun for a while, but deep down, we know it sucks, and later on, it's no fun.
When WotC makes a slow set, it's boring for a while, but later on, it makes us realizes that speed is not necessarly good.
It's easy to tell the correct speed of Magic.
Garfield intended Magic to be a game playable during lunch breaks, at home, and when visitng friends. It's game length was to fit in that happy zone neither too long, nor too short, specifically, about 7 minutes.
Urza was too fast. Games took three minutes. Two of which was the final turn.
Masques was too slow. Fifteen-plus is simply too much time for one game. It hurt tournaments. It didn't affect casual, since Urza cards were floating all over the place.
We are now stabilizing again.
We have learned what we want.
We want Beta back.
We want junk. Junk, but playable junk.
We want power. Power, but power thwarted by junk.
We want speed. Speed, but speed thwarted by power.
We want balance.
We want chance.
We want strategy.
We want Magic.
We want cards that always have a use.
We want to have fun.
Let's hope Garfield brings back Beta, Unlimited, and Revised with Argon, Boron, and Carbon.
