Tectonic Giant punishes every attack into it — either dealing 3 damage to each opponent or letting you exile the top two cards of your library and play one of them, both modes relevant every combat. The rate is real for four mana, and Aegar, the Freezing Flame turns that damage trigger into guaranteed card draw by fulfilling the 'excess damage' clause on any creature with exactly one toughness.
Best Commanders
Commanders with the highest synergy

Aegar, the Freezing Flame
Aegar, the Freezing Flame runs Tectonic Giant in over 62% of decks because the Giant's attack trigger deals 3 to each opponent, routinely dealing excess damage to any creature with a single toughness and converting every swing into card draw off Aegar's ability.

Wulfgar of Icewind Dale
Wulfgar of Icewind Dale doubles every attack trigger, so Tectonic Giant either pings opponents for 6 total or lets you exile and play from the top of your library twice — both modes scale absurdly with Wulfgar's doubling effect.

Faldorn, Dread Wolf Herald
Faldorn, Dread Wolf Herald cares about casting and playing cards from exile, so Tectonic Giant's second trigger — exile the top two, play one — generates a Wolf token off Faldorn every time it connects.

Neheb, the Eternal
Neheb, the Eternal converts precombat damage into mana, and Tectonic Giant's 3-damage-to-each-opponent trigger fires before combat damage resolves, feeding Neheb a meaningful burst of red mana heading into the second main phase.

Rionya, Fire Dancer
Rionya, Fire Dancer creates token copies of creatures at the beginning of combat, and stacking extra Tectonic Giant triggers means multiple exile-and-play windows or a wall of 3-damage pings that opponents simply cannot ignore.

Tectonic Giant is a Commander card through and through — four mana for a 4/4 that demands an answer is fine but not exceptional in 60-card formats where the format's best creatures at that slot are faster and more immediately threatening. In Modern and Pioneer the competition at four mana is brutal, and a trigger that requires opponents to attack into the Giant rather than going under or around it is too passive. Commander is where it lives: multiplayer means the 3-damage-to-each-opponent trigger hits three or four people simultaneously, the card advantage mode matters over long games, and the Giant's natural resilience to combat discourages attacks in ways that single-target formats never replicate.
