As you lose the Monarchy whenever you're damaged by an opponent's creature in combat, Spore Frog combined with Dawnglade Regent and Meren of Clan Nel Toth makes you unable to take combat damage (or rather, it does but that damage is prevented in full)
The best-case scenario is that youve got a strong multicolored board already, and Guideline Station will just make that stronger
Then you need two copies of Myr Retriever, a rather forgettable card that lets you bring back another artifact card from your graveyard to your hand
Its been over $30 in the past, and as a Reserved List card, we know hes not getting reprinted
One of the things I love about casual EDH is that there is a lot of space for interesting, janky and even "bad" decks, provided you are playing in a group where the power level allows those suboptimal decks to actually have a game and do stuff
