This is awkward without land, because I really want to lead with Thorn, but then I shut off my own Sol Ring until the following turn, which thus leaves little pressure (not knowing the thalia is there) on your 2nd turn, so let's evaluate:
- Turn 1, you lead with Mana Crypt and Mox Pearl, then Sol Ring, and then play the Thorn. In theory, you follow up with Revoker on Black Lotus as that's the scariest turn 1 thing they can do.
-Turn 2, you draw Thalia, but you cast Loadstone Golem.
- Turn 3, you cast Thalia.
- Your opponent can Mistep the Sol Ring (assuming they keep this in because they're a Mentor deck and you have Plowshares post-board as your only way to effectively stop their Mentor). This leaves you with no turn 2 play (again, not knowing aboutThalia).
- Your opponent Forces your Thorn. I think this is a pretty fine situation for you, as you follow up with Golem if they don't Vintage you on their turn 1, after removing 2 cards from hand.
- They do both the above. You're in a WORLD of hurt now.
- You lead all the way with Lodestone.
- They Force lodestone. You have a Thorn + Revoker to follow up (and then draw Thalia for the real spice)
- They allow it to resolve, then play a mox or two, plow it etc, or just get ahead of you on mana.
There's other options, But I think the two I outlined are the two most reasonable.
I would go with the following line:
Mana Crypt, Mox Pearl. Sol Ring. Regardless of Mistep or not, I play Thorn. If it isn't mistepped and Thorn isn't FOWed, I play Revoker on Lotus, and then follow up my turn 2 with Golem. Basic @Twaun007 Shops Philosophy applies here: I always want to do 2 disruptive things on Turn 1.
If they Misstep the Sol Ring, Thorn gives them a very small shot of just doing Vintage things on their turn 1.
If they Force the Thorn, Revoking Lotus gives them a very small shot of just doing Vintage things on their turn 1.
If they Misstep the Sol ring AND force the Thorn, their 4 Card hand + Draw Step gives them a very small shot of just doing Vintage things on their turn 1.
