Abzan Amulet-turn 3 kill-competitive combo deck (Modern)

it's quite difficult to understand if you don't know how amulet deck works, anyway i'll explain it:
-turn 1: basic land for amulet of vigor
-turn 2: another basic land to play noble hierarch or elves of deep shadow
and that was easy, now
-turn 3: don't put any land, and tap 2 for the summer bloom. now you can play 4 lands this turn. play a ravnica's double land (for instance selesnya sanctuary) and return to your hand a basic land. this land should come in play tapped, but you untap it for the amulet, so you can tap it to get 2 mana. now play the second land of the 4 you can play this turn, and play another ravnica's double land, for instance golgari rot farm, thanks to whom you can return to your hand selesnya sanctuary. untap this land for the amulet and tap it to get 2 other mana. now you have 4 mana. put the third land, selesnya sanctuary (returning golgari rot farm to your hand), tap it and get other 2 mana, so you have 6 mana. now put the fourth land, and it's golgari rot farm (return a basic to your hand) and tap it to get 8 mana total. now tap noble hierarch or elves of deep shadow to get mana, so you have 9. use 3 mana to cast your tainted remedy, and the last 6 for the beacon of immortality targeting your opponent. instead of gaining X life where X is his life total, he loses X life where X is his life total for the tainted remedy.
because of this combo (easily get 8 mana or 6 on turn 2) i have put these other 6/8 mana cost cards
