1- Have Pili Pala.

2- Have Paradise Mantle.

3- Equip mantle to the pili-pala. Congratulations for your new fidget spinner.

4- Use PP for mana and cast Legolas Quick Reflexes on the PP. Now you have a board wipe.

5- Tap PP for mana, do 1 damage, pay 1 extra to untap it and get 1 mana.

6- Now you are mana neutral and can tap and untap your PP as much as you want. Deal 1 damage each loop.

...

By adding [[Polyraptor]] or [[Stuffy Doll]] you could even win the game!!

Edit: I Clearly missed the joke title: Make every creature leave the battlefield by tapping and untapping your PP

1- Have Argothian Treefolk in play (3GG)

2- Have Mycosynth Lattice in play (6), now everything is an artifact.

3-Play Pariah's Shield (5)

4- Equip to the Treefolk (3)

5- Now any damage you take is redirected to the treefolk, but since everything is an artifact, all that damage is prevented. Treefolk lives forever, you live forever*

I post here because honestly all these games are awesome, and some are not well known

They almost always choose DnD

They always have the same problems (people are confused, sessions last longer than expected, rules get in the way of the dynamic)

They almost never question the system itself, rather they say that players are somehow the factor that needs some solution or strategy.
