Ms Bumbleflower easy mode (EDH / Commander)

Everyone's new favourite rabbit but with a mean twist.

Lock your opponents out of casting spells during your turn with Silence, Grand Abolisher, Mandate of Peace, Kutzil, or Teferi, then cast a ridiculous amount of spells using one of the many possible combos in order to force your opponents to draw cards until their libraries are empty and they lose the game. Combos include:
a) Food Chain + Eternal Scourge or Misthollow Griffin: exile the creature to Food Chain to make mana, use mana to re-case the creature from exile. This also makes infinite mana, so if Ms Bumbleflower isn't already on the board you can cast her no matter how expensive her command tax.
b) Shreiking Drake + Smothering Tithe: once everyone's tapped out you can guarantee a treasure token each time you cast the drake, and use that token to pay for it next time.
c) Shreiking Drake or Whitemane Lion + Intruder Alarm + mana dork(s): if you can just use mana dorks to cast the creature, when it enters it untaps all creatures, and returns itself to your hand ready to cast again. If you have more dorks than the creature costs then this also nets infinite mana.
d) Displacer Kitten + Teferi, Time Raveler + Jeweled Lotus or Mana Crypt or Sol Ring: use Teferi to bounce your mana rock back to hand, when you re-cast it trigger Displacer Kitten to blink Teferi, resetting him and allowing you to return the mana rock to hand again. This loop can net you mana but also draws you a card, so only do this until you draw into another finisher like Finale of Devastation.

Other plays worth remembering:
Glen Elendra Archmage can be reset by putting a +1/+1 counter on it with Ms. Bumbleflower, allowing you to keep using it to counter spells.
Nadu can also be triggered by putting +1/+1 counter on with your commander.
You can safely exile Misthollow Griffin to Force of Will or Force of Negation, and cast it from exile later. Both it and Eternal Scourge can also be exiled to Gemstone Caverns if you happen to start the game with both.
