This deck exploits the
Dormant Sliver, which can allow you to draw your entire deck and end games mercilessly. There are a few infinite combos. First, one for the Queen. Requires a mana sliver (Gemhide or Manaweft), a haste sliver, a
basal sliver, the Dormant, and the Q. Make a token off of the Queen. Draw a card. Tap the token for any color mana, then sac it for BB. Rinse and repeat. (Nice to have the Quick and the Crystalline in there to prevent any interuptions) Combo 2. Requires two one drop slivers, (Mindlash or Screeching in any combination), one in hand, and one in play, a mana sliver, a haste sliver, the basal, a pulmonic, and a dormant. Tap one of the one drops for mana. Sac it. Put it on top of your library due to the Pulmonic. Play the other one drop, which draws you the other one drop from your library. If you want to not be messy, use the same combination except with a psionic in play instead of the mana sliver. With an arbitrarily large number of slivers, you can mindlash your opponents, screech their library, then necrotic their permanents.
If you wanted to sideboard in the Ameoboid Changeling for the Sedge, you could then make every creature your opponent controls a sliver, then
enslave them with the Overlord. However, if you do this, mindlash them hellbent first so they cannot respond after you
detonate the
Crystalline Sliver. Harmonics are in the Side to deal with artifacts and chants.
This deck IS fun to play, but NOT fun to play against, so be warned.
