The Commander
Companion — Each permanent card in your starting deck has an activated ability. (If this card is your chosen companion, you may put it into your hand from outside the game for 
as a sorcery.)
Abilities you activate that aren't mana abilities cost 
less to activate. This effect can't reduce the mana in that cost to less than one mana.

: Target creature can't block this turn.
Guide
Gameplan
Zirda turns activated abilities into a value engine by knocking off every non-mana activation, then chains those discounts into card advantage, recursion, or an outright combo. You deploy cheap permanents with strong tap/activate abilities and grind incremental advantage until you assemble an infinite loop or simply out-activate the table. Many builds use Zirda purely as a combo piece while playing a different RW commander, but as commander she anchors an abilities-matter midrange deck.
Strengths
- Massively reduces the cost of expensive activated abilities, enabling planeswalker-style engines
- Enables several compact infinite combos (notably with Basalt Monolith and Grim Monolith)
- Cheap, recastable commander that immediately impacts the board
- RW gives strong artifact and creature ability support plus protection
Weaknesses
- The reduction can't go below one mana, so it does nothing for one-mana abilities
- Heavily reliant on Zirda staying alive; she's a removal magnet
- RW lacks card draw and ramp depth compared to other color pairs
- Combo-centric lines can be disrupted by graveyard hate or artifact removal
Key Cards
- Basalt Monolith — With Zirda its untap cost drops to , and paired with a mana doubler or Rings of Brighthearth it goes infinite.
- Grim Monolith — Same untap discount as Basalt, giving you infinite colorless mana with the right outlet.
- Staff of Domination — A flexible win engine whose abilities all become far cheaper, enabling infinite mana payoffs and card draw.
- Walking Ballista — A natural mana sink and removal/win outlet once you generate infinite mana.
- Rings of Brighthearth — Copies activated abilities and closes combos with Zirda's discounted untap costs.
- Sword of the Animist — Cheaper equip and a mana ability that ramps your ability-heavy plan.
Upgrade Path
Tighten the combo package: add Rings of Brighthearth, Basalt Monolith, Grim Monolith, and a payoff like Walking Ballista or Staff of Domination so any one piece plus Zirda closes the game. Improve mana with fast rocks and consistency with tutors like Enlightened Tutor and Gamble, and add protection (Lightning Greaves, Deflecting Swat) to keep Zirda alive through removal. Trim purely incremental abilities that cost one mana, since Zirda's discount whiffs on them.
