This is maybe another Peasant Cube type interaction, but putting Well Rested on any mana creature is a great way to get some more value out of your Llanowar Elves as the game progresses
At the start of your combat step, each Merfolk creature you control explores, either digging you through lands or letting you set up the top of your deck with the best card possible
A two for one against some decks, and if your deck wants to sacrifice artifacts, you could do worse than Gearbane here
In fact, if its not in your opening hand, this card is honestly quite bad, as its essentially just a Wastes without looking as cool
One of the biggest payoffs I can see here is Exocrine
Theyre also both pretty solid cards in general, so dont be afraid to play them alone
