#3 Crystal Skull, Isu Spyglass Crystal Skull, Isu Spyglass is an amazing artifact for any Commander decks that have a lot of Historic permanents
It reduces analysis paralysis for new players looking for early direction while eliminating a major fraud axis for bad actors
It's the Moana - Adventurer of Land and Sea card which, if you're a Lorcana player or collector, you will have almost certainly seen already
The only way around this is if you can find a way to activate the forecast ability, remove the card from your hand, then return it and activate the ability again all in the same upkeep
The amount of mana it generates, combined with being a win condition on its own, is just massive for a Modern card
I also like this in Azorius Flyers with evasive aggro beaters like Judge's Familiar that you can now win with in one hit unlike the beefier Green stuff which is a faster kill
