Theres also Dockside Extortionist, a card so good its one of the very few banned in Commander, generating X treasure tokens where X is the number of artifacts and enchantments your opponents control (so you can see why thats OP when you have three opponents rather than one)
For example, if you want to play with decks about as strong as precons without limiting yourself to an off-the-shelf deck, you'll want to build and play at bracket two
And looking at the rates, doing things this way is exorbitantly expensive and not at all worthwhile
Of course, you dont actually need to always force yourself into four or five colors to build around these synergies
Its still the purest mass board pump effect you could ask for
Even using cards that allow the Trainer to see their opponent's hand or mess with their deck in some way is more effective than Pokdex
