Svega, the Unconventional

Landfall — Whenever a land enters the battlefield under your control, put a loyalty counter on target planeswalker.
[−2]: For each planeswalker type among planeswalkers you control, create a 1/1 Attendee creature token that's all colors.
[−X]: Choose an Elspeth, Teferi, Liliana, Chandra, or Garruk planeswalker card name with mana value X. Create a copy of the card with the chosen name. You may cast the copy without paying its mana cost.
Svega can be your commander.
