Whenever Pako attacks, exile the top card of each player's library and put a fetch counter on each of them. Put a +1/+1 counter on Pako for each noncreature card exiled this way.
Pako and Haldan want to attack early, exiling cards from every library to fuel a snowballing fetch counter pile, then cast those exiled cards for free. You grow Pako fat off noncreature exiles while Haldan lets you play the noncreature cards you've exiled, generating massive card advantage. Close games by either swinging with a giant trampling Pako or chaining the free spells you steal off opponents' libraries.
Explosive, unbounded card advantage that draws from every player's deck
Pako grows into a real threat with haste, ending games via combat quickly
Haldan turns exiled noncreature cards into free spells, effectively a second engine
Synergizes with extra-combat and big-mana payoffs to spiral out of control
Heavily commander-dependent; losing Pako repeatedly stalls the whole plan
You can only cast cards with fetch counters, so removal of your commanders strands them
Vulnerable to board wipes and targeted removal on Pako before it connects
Cards exiled are random, so consistency and a reliable backup plan are shaky
Symmetrical exile can occasionally help opponents see cards too
Repeatable extra combats let Pako trigger multiple times to bury opponents in counters and free spells.
Lean into trample and pump (Berserk, Rancor, Embercleave) plus extra-combat enablers (Aggravated Assault, Combat Celebrant) so Pako converts counters into kills fast. Add strong ramp and cost reducers to reliably cast the noncreature cards Haldan unlocks, and include commander protection like Heroic Intervention and Lightning Greaves. For consistency, prioritize cheap evasion and haste support so Pako connects on turn three or four before the table sets up defenses.
