Jace, Cunning Castaway + Nicol Bolas, Dragon-God + The Chain Veil Combo

All permanents on the battlefield.

Nicol Bolas has at least four loyalty counters on it.

available

Activate The Chain Veil by paying and tapping it, allowing you to activate each planeswalker's loyalty abilities an extra time this turn.

Activate Nicol Bolas using Jace's first loyalty ability by putting a loyalty counter on it, causing you to loot whenever a creature you control deals combat damage to a player this turn.

Activate Nicol Bolas using Jace's third loyalty ability by removing five loyalty counters from it, creating two copies of Nicol Bolas.

Repeat from step 2 using a Nicol Bolas token instead.

Once you have infinite Nicol Bolas tokens, each one that can still activate a loyalty ability may do so, allowing you to draw any number of cards and cause each opponent to exile that many cards from their hand and/or permanents they control; and creating any number of Illusion creature tokens by using them to activate Jace's -2 ability.
