Well... that seems like a deck that would probably win against most Manalink decks (played by Manalink's AI), so it probably doesn't need much improvement anyway
Nevertheless, here are some ideas to consider:
1) It might be unnecessary to have the two combo locks (
Stasis +
Blind Obedience, along with
Energy Field +
Rest in Peace), particularly if you are packing Enlightened Tutors to fetch for the pieces you need (though, yeah.. I guess redundancy can be good too);
2) I'd swap the
Unsummon by some card that can also bounce the
Stasis back to your hand, if needed (like
Boomerang or
Echoing Truth);
3) I'd probably swap the
Psychic Barrier and possibly the
Negate by
Arcane Denial (underlying logic: you drawing cards is good, to try to get lands to pay for
Stasis or something to bounce it... opponent drawing cards is irrelevant if he is locked or about to fall into the lock... also, it's easier to cast than
Psychic Barrier and more versatile than those two counterspells); the
Deprive I would swap out too, if they weren't so useful to bounce
Stasis back into your hand;
4) The land count might be a bit too low (maybe adding some Flooded
Plains wouldn't hurt), but that's something that you should determine by playtesting anyway;
5) The
Serra Avenger idea is nice, and I like it, but it might not be the most efficient kill condition... running zero creatures is often better than running a single creature, since it invalidates all of opponent's creature removal cards (i.e. card advantage in a control deck == good)... this deck could just as well run a pair of
Elixir of Immortality as "kill condition" (if you like neverending Manalink duels, that is
).
Good deck, though
