7-8 colorless mana is the reason Mana Drain and Decree were paired up. Agreed on Tinker/DSC, however many more decks nowadays have oodles of bounce for him, making it harder to keep him out to win. To me, it just seems that many men attacking over 4-5 turns when you have a full grip is better than expending all resources on keeping one man in to swing for two turns.
EDIT: I would use Decree in Control Heavy Metagames, with Tinker/DSC as backup. Uncounterable dudes with no Card disadvantage is tech.
You seriosly want to use mana drain to make 1/1's?....I generally tend to put that mana to good use and draw some cards, go broken or something.
Keeping DSC on the table isnt all that hard, you realize that you dont have to go "Turbo DSC" in every game, right?
Ive tried DoJ...while the card itself might be fine, its just not my style..it seems way to slow and clunky..and its off-color.
