infinite mill (Modern)

Get a ruin ghost, a hedron crab, and a retreat to coralhelm out. Then start the infinite landfall loop using Hedron Crab's mill ability.

Mill possibility on turn 4:
1) Island (tap)/Hedron Crab
2) Plains (tap with Island) (mill 3)/Ruin Ghost
3) Mana (whatever-tap with Plains and Island) (Mill 3)/Retreat to Coralhelm
4) Tap Plains to Tap Ruin Ghost to Exile Plains/Return Plains untapped (mill 3)/Use Retreat to Coralhelm ability to untap Ruin Ghost/Repeat until all cards are milled.

Altar of the Brood can be utilized instead of hedron crab in the same way.

If you only have the Ruin Ghost and Retreat to Coralhelm out, you can infinitely scry until you get the Hedron Crab our the Altar of the Brood. Next turn would be the win.

Alternate win condition- Retreat to Emeria instead of Hedron Crab/Altar of the Brood. Create infinite 1/1 Kor Allies that you can grow infinitely until end of turn.

The Judge Unworthy and Sigiled Starfish are in there for both their defensive capabilities and their ability to scry.

Drift of Phantasms and Idyllic Tutor are for searches, and Drift of Phantasms could also be a good blocker if that is needed.

Weaknesses- Swarm and Trample. Possibly Burn as well.

Ghost draws have the players out and ready between 5 and 8 turns regularly (in my testing)

I have played the proxied deck once, and it lost to a green elf mana ramp/eldrazi deck. I was not able to get Retreat to Coralhelm out before the eldrazi were up and running. It played well though.
