I have spent quite a bit of time tinkering with Tinker, and I still not convinced it is an fantastic path to go down. In theory Tinker creates an interesting draft subgame, and acts as a powerful and versatile tutor for a range of effects. In reality, most decks have 1-2 cards that are kind of worth getting, and the flexibility of the card is never really showcased. While this may be entirely due to my targets, Tinker often acted as a method by which slower decks would access controlling cards ahead of schedule. They didn't use it to turn a corner, to start trying to win the game, rather just used it to lock down the game a little bit more. Trading a mana rock for a
Gilded Lotus to ramp and fix (which was neat, and I did see on hell of a turn 3 play of 'tap
Mindstone and 2 lands for
Tinker, get
Gilded Lotus, land,
Wrath') and a turn 3
Staff of Nin is a neat trick for a control deck, but I am not sure it is worth both the deck building contortions and often the card investment for these outcomes.
I don't think I ever saw someone Tinker away an expended
Tangle Wire, or grab a
Phyrexian Revoker (
Duplicant however was a common target) or a
Nevinyrral's Disk (too slow) or any of the super cool plays I had in mind. The Masticores were also hugely underwhelming.
I have been trying to think of Tinker as closer to a reanimation spell, but due to the artifact restriction, the range of targets are limited, and a lot of the strong ones come too close to 'Ok, I win', or are simply cards I don't really want in my environment (I am looking at you
Wurmcoil Engine...)
I hate to take the wind out of your sails, and I am interested in where you choose to go with it, but in my experience it has been a little underwhelming. If you are looking at my thread for inspiration, I would probably be advising that you can push the targets a little harder than I did. Possibly something like
Platinum Angel or
Platinum Emperion was where I wanted to be.
Bosh has been ok, but is quite a removal check. When you get to untap with him, he represents so much damage, and feels kind of similar to
Kalonian Hydra, with that said, that effect is much more tolerable at 8 mana instead of 5. I suppose you could argue he is more synergistic, in that he can fling other artifacts or the like, but that is like pointing out that Kalonian Hydra pitches to
Force of Will.
