How it works
Activate Chandra's second loyalty ability by putting zero loyalty counters on it, creating two 1/1 Elemental creature tokens with haste.
When the Elementals enter the battlefield, Intruder Alarm triggers twice.
Resolve the first trigger, untapping all creatures.
Activate Aphetto Alchemist by tapping it, untapping The Chain Veil.
Resolve the second Intruder Alarm trigger, untapping all creatures.
Activate Aphetto Alchemist by tapping it, untapping target artifact or creature.
Activate Ashnod's Altar twice by sacrificing the two Elemental tokens, adding CCCC.
Activate The Chain Veil by paying 4 and tapping it, allowing you an additional activation of your planeswalkers' loyalty abilities this turn.
Repeat.
This brilliant engine transforms the token-generating potential of Chandra, Acolyte of Flame into a self-sustaining loop, fueled by the explosive mana production of Ashnod's Altar when you sacrifice those freshly made Elementals. Each batch of tokens feeds Intruder Alarm's global untap triggers, which simultaneously refresh Aphetto Alchemist and ready your board for more action. Meanwhile, The Chain Veil steps in to bypass normal loyalty restrictions, allowing Chandra to repeatedly flood the board with new tokens while you reap boundless sacrifices, mana, and untaps.
