Infinite commander

[Ahamay]

 {Palinchron} +  {Mana Flare} to go infinite mana then summon your commander  {Niv-Mizzet, Dracogenius} for the kill. As long as your mana base is six lands untapped to start (with two island and one mountain) this works.

I hedge with {Winding Canyons} or  {Vedalken Orrery} and do it on the end step to make sure I have the best shot at pulling it off

If you end up drawn out of your library have some answers to skip draw if they {Trickbind} you and then just do it again next turn.

Not sure if anyone already mentioned this one.

{Omnath, Locus of Rage} +  {Perilous Forays} +  {Amulet of Vigor}

{Omnath, Locus of Rage} +  {Perilous Forays} +  {Amulet of Vigor}

That's nice filtering, even if it's limited to your lands with a land subtype.

Inspired has become quite abusable with  {Cryptolith Rite} + {intruder alarm}.
Take  {God-Favored General} + 2 other creatures. Untap, triggering the ability. Pay the mana by tapping the three creatures, get tokens.
Infinite tokens and untap triggers. Add {prodigal sorcerer} for a win right there.

EDIT: Easier way is {felhide Spiritbinder}. Since the copy has haste, it can be tapped for mana, requiring only {1} as setup cost.
