Rowan is a mono-red planeswalker commander who controls combat and punishes attackers. Plus her up ability to force opponents into bad attacks or set up your own alpha strikes, use the -2 as repeatable creature removal/board control, and grind toward the -8 emblem that doubles your activated abilities. You protect Rowan with aggressive creatures and group-slug damage while leaning on red staples to close games.
Repeatable removal via -2 that sweeps tapped creatures, great against go-wide and aggro boards
Combat manipulation forces opponents to attack each other or into bad blocks, slowing the table
Game-ending -8 emblem that copies every nonmana activated ability you control
Loyalty starts high (mana value 6 means she enters and can plus immediately to 7) making her sticky
Mono-red has weak card advantage and limited interaction outside of damage
Planeswalkers are vulnerable to being attacked down before abilities matter
No inherent ramp or recursion, so red's reach is capped
Forcing opponents to attack can backfire and pad your own board's threats only situationally
A red planeswalker whose dice-roll activated abilities get copied by Rowan's emblem for absurd value.
Pair her with Will Kenrith to splash blue for card advantage and counterspells, dramatically improving consistency over mono-red. Add loyalty doublers like Doubling Season and The Chain Veil-style enablers to reach -8 faster and chain ability copies. Round out with fast mana (Sol Ring, Mana Crypt), planeswalker protection (Norn's Annex, ghostly defenders), and a clean activated-ability combo to convert the emblem into a reliable kill.
