You've got balls, but I've got Disenchant.
Like you've said, Lodestone Myr, which seems like all you've got, is basically open to any removal in Type 1.
Yes I do, and yes you might, and yes it is. But you're ignoring the controlling aspect of the deck. Trinisphere makes Disenchants cost three. 5 Strips and Welder (against artifact mana) can usually deny white when it's the off-color in a deck. Also, this deck aims to out-accelerate and outdraw the other guy.
And really, how is this better than straight Slavery?
Really, I don't know. I have not played Slavery much. But, based on the lists I've seen of Slavery, I would say they are very different decks, although I did obviously use the core of Slavery in here. Slavery is much more of a prison deck with a slower win and more control, and this is much more a soft-lock deck with a combo win. I'm not even sure the two are really comparable.
and also, the aim of slaving someone is to kill that someone with his own deck
That's the idea of Slaving someone in Slavery. In here it's a setup card. It can be used differently in the two decks, you know.
Perhaps I'll change the name of the deck to prevent future posters assuming this is a Slavery variant with Trinisphere instead of a Trinisphere deck that happens to run Slaver.
