Sivitri lives in the command zone and immediately starts tutoring up your best Dragons with her -3 while her +1 fogs away aggression and protects your board. Cast efficient Dragons, ride her +1 to keep her loyalty climbing toward the -7 wrath, then close with evasive flying beaters or a Dragon-fueled combo.
Repeatable Dragon tutoring gives consistent access to bombs and answers
+1 is an excellent pillow-fort effect that protects her and you
Ultimate is a one-sided board wipe in a Dragon deck
Cheap four-mana commander that's hard to attack down
Dimir colors add strong card draw, removal, and counterspells
No built-in card advantage beyond tutoring one card
Loyalty is vulnerable to direct planeswalker removal and burn
Blue/black lacks the red ramp and payoffs of typical Dragon tribal
Slow start if your Dragons are top-heavy and ramp is light
Relies on protecting a planeswalker, which decks with hexproof-ignoring removal punish
