Every card represents some piece of the set's story, even if it's simply a single, unnamed soldier charging into battle
If this is the second time this ability has resolved this turn, draw a card
Cards like Courser of Kruphix and Tireless Tracker are exceptional here but will be snatched up by any green deck, so it might be good for some of those payoffs to demand/reward a stronger commitment I'd consider Wayward Swordtooth as a more balanced version of the extra lands effect with a subgame that's fun and attainable (and not just by you!) #3 I think Simic Lands is a great archetype that won't be leaving my cube any time soon
The Metalcraft ability reduces the equipment cost to 0 as long as three or more artifacts are controlled
Garnet, Princess of Alexandria A solid 2/2 for 2 with lifelink, Garnet shines it up by her interaction with Sagas by keeping them around longer and growing, working especially well with Saga creatures
As is, I dont see why the price is as high as it is and Id be shocked if this held above $5, never mind $10
