Primary Strat: Work in progress Commander deck built around the concept of assigning equipment (like Spy Kit and psychic paper) to the opposing players and their permanents using your Commander's ability (Ardenn, Intrpid Archaeologist), renaming all the card types they have using that equipment or causing other detrimental effects, then comboing off by doing board wipes, exiling, and card removal through spells like Declaration In Stone. You equip a creature, then target it with a spell like Declaration in Stone, and basically exile every non-legendary creature on the battlefield, which can include lands and lots of other things that have the creature type. Another way to do this is assign equipment directly to the opponent and use a spell like Eradicate. This will exile everything in their hand, graveyard, or library that shares the name of that thing. You basically force this equipment on your opponent's creature, then you eradicate it, and that essentially removes every single non legendary creature from their play and from their entire deck (if you go up against a big green stompy deck, it's kind of over for them).
You obviously don't want to do this to yourself, but if you have Ardenn, Intrepid Archaeologist in your deck or as your commander (this is the working model; I can partner him with whoever else), then attaching equipment is easy. Declaration in Stone, by itself, does not work with Spy Kit very well. However, with Ardenn, Intrepid Archaeologist as one of your commanders, you can force Spy Kit onto any permanent on the field, then play Declaration in Stone. That is the combo. Yes, it's only one player at a time, but you use it to target your biggest threat first. Once they have no field, they have to rebuild, and they become massively vulnerable.
Second strat: maybe consider attaching equipment to one of my creatures and swapping control to another player for an additional attack vector. (Magnetic Theft?)
Third Strat: There are stacky ways to kind of approach this as well, like...Cornered Market and Bazaar of Wonders. These prevent your opponents from playing anything but legendary creatures. It's kind of gross
Fourth: Get intermittent, regular effects throughout the game. Like Evil Twin, for example. Equip your Spy Kit onto this evil twin, and now it has the name of all non-legendary creatures. Now it can destroy any creature it wants (non legendary) for its activated ability. *** I could consider also adding additional shenanigans with untap effects that will let me do this a couple times.
Fifth: Finally, an artifact that I can gain a lot of advantages on is an artifact called Bubbling Cauldron...The first ability is whatever, but you really get utility out of its second ability. Any creature you control with something like Spy Kit attached, you can sacrifice it, gain up to 12 life, and ping everyone for 4.
These small combos fill out the theme for this deck, but the rest of the deck is designed to gain incremental effects through tokens and legendary creatures. The point being, the deck should be built with legendary creatures that won't be hit when you target the field with things like Declaration in Stone to make it only a one-sided board wipe. Similarly, tokens do not have names that are included as part of a card like Spy Kit since they're technically not creature names. It's beneficial to flood the field with tokens that won't be impacted by the Spy Kit combos.
Example combo: Generating tokens through a card like Jadar by having it generating a token, putting Spy Kit on it, then sacrificing it to bubbling cauldron. You can repeat that cycle turn after turn after turn until it's dealt with or you win the game.
