I don't like eidelon in goblins. It doesn't fit our gameplan. We can't cast a t2 Eidelon AND put 7 damage on the ANT player like Burn can. I feel we need to tax and disrupt Storm decks. And Eidelon is pretty lame against non-Storm combo.
Leyline sorta disrupts but doesn't tax at all, so I'm just not a fan. Also being a dead draw makes it unplayable to me.
Mindbreak Trap is actually totally fine and good against Storm, but it's too narrow against the other combo decks.
Surgical Extraction is a difficult card for me to side in against Storm or combo because its effect is often redundant once they start going off unless you're a mind reader. I'd usually rather just have a goblin card in hand. I just don't know if Surgical has ever won me a game against Storm.
Thorn of Amethyst might be better than Trinisphere now. Or maybe even Sphere of Resistance. Thorn and Sphere are easier to play t1 and wayyyy easier T2 than 3ball. SoR hits Elves too. It's also better in multiples. Hmmmm....
