My original idea was to build an artifact cube with Scars of Mirrodin block cards and Kaladesh block cards, but given how parasitic Infect and Energy are, I am better off building a cube only with Kaladesh block cards, and a few enablers
4.Wizards of Thay Another four mana value Creature, the Wizards of Thay offer some added value to spellslinger decks
The One Ring is exactly the type of card that looks inoffensive at first glance, but can actually be quite powerful
Myr Incubator is fun, too
The other downside to this one is that unless you can remove it, you are obligated to pay the life and draw a card, so it is possible to lose to your own Phyrexian Arena
So you could make an argument that Magics designers didnt anticipate that Tinker would be used to quickly and easily bring ultra-powerful Artifact Creatures into play way too early in the game
