Ichormoon Gauntlet + Oath of Teferi + Teferi, Master of Time

Overview

Ichormoon Gauntlet grants additional loyalty abilities to planeswalkers you control (those granted abilities are loyalty abilities under ). Oath of Teferi's text attempts to let you activate loyalty abilities of planeswalkers you control twice each turn rather than only once, and Teferi, Master of Time's text lets you activate Teferi's loyalty abilities any time you could cast an instant (so off your turn) (see ). However, per the cited ruling, only one loyalty ability of each planeswalker may be activated per turn, no matter how many it has gained (Ruling [2023-02-04]).

Step 1

Ichormoon Gauntlet’s static text grants planeswalkers you control new loyalty abilities (the [0]: Proliferate and the [−12]: Take an extra turn after this one). Those are loyalty abilities because they have loyalty symbols in their costs ().

Step 2

Oath of Teferi’s static effect allows you to activate loyalty abilities of planeswalkers you control twice each turn rather than only once (this is a change to how many activations you may perform each turn).

Step 3

Teferi, Master of Time’s own text allows you to activate his loyalty abilities any time you could cast an instant (so not restricted to your main phase) — that modifies the usual timing in for that specific planeswalker.

Step 4

When you attempt to activate a loyalty ability on that Teferi, check the loyalty cost and the number of loyalty counters on the permanent. A loyalty ability with a negative cost can’t be activated unless the permanent has at least that many loyalty counters ( and ).

Step 5

Because of the WotC ruling (Ruling [2023-02-04]), only one loyalty ability of that specific Teferi may be activated during the turn. Even though Oath of Teferi allows you to activate loyalty abilities twice each turn, you cannot use both activations on the same planeswalker in the same turn per Ruling [2023-02-04].

Step 6

You may use the other activation permitted by Oath of Teferi on a different planeswalker you control (a different planeswalker is not limited by the 'one loyalty ability per planeswalker per turn' rule for that other permanent).

Step 7

If an activation causes Teferi’s loyalty to be reduced to 0, the planeswalker is put into its owner’s graveyard as a state-based action () the next time state-based actions are checked.

Resolution

Because the WotC ruling (Ruling [2023-02-04]) limits activations to one loyalty ability of each planeswalker per turn, you may activate a given Teferi’s loyalty ability only once that turn—even if Ichormoon Gauntlet has granted extra loyalty abilities and even if Oath of Teferi would otherwise let you activate loyalty abilities twice each turn. Oath still affects how many planeswalker activations you may perform overall (it permits activating loyalty abilities twice each turn rather than once), but you cannot use both activations on the same planeswalker in the same turn due to Ruling [2023-02-04]. Teferi’s permission to activate his loyalty abilities at instant speed remains in effect (so the one allowed activation of that Teferi may be done any time you could cast an instant) (see ). Any loyalty ability you choose to activate (including those Ichormoon grants) must meet the normal loyalty-cost and loyalty-counter requirements (see and ), and if a planeswalker’s loyalty reaches 0 it is put into its owner’s graveyard (see ).
