Theyre also both pretty solid cards in general, so dont be afraid to play them alone
These cards have a direct effect over the game and if you want to get rid of them or interact with them in any way, youre going nowhere fast
A two for one against some decks, and if your deck wants to sacrifice artifacts, you could do worse than Gearbane here
Finally, if you're looking for removal that can also act as a finisher there's Comet Storm, the newest, sauciest fireball variant
One of the biggest payoffs I can see here is Exocrine
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
