I like it. It's not as eternal as buyback is, but they made it cheaper. Add some card drawing or hana kami to your splices and you can keep on going. Counterspells get rid of the played spell, not the splices ones, so in that way it's more resistant to counters than buyback was. The 2 important questions: how many arcane spell (with and without splicing) will there be in Betrayers and Saviors? And how good (or broken.... ) will they be? It is a mechanic that can't be (easily) combined with other cards, so I hope they'll print a boatload more of it Reweave is very fun by the way. I once prevented 2 players from getting their urzatron complete (tower, mine, powerplant) by letting them sac their tower, hehe.
