Enigma

When Enigma’s activated ability resolves, you will create a Spectral Shield token that will enter the arena with a +1 counter on it.

Effects that cause a player’s cards and tokens to lose and can’t gain names (e.g. Amnesia) do not prevent Spectral Shield tokens from being created when resolving effects on other cards. Enigma’s activated ability will still resolve under these effects, resulting in a Spectral Shield token being created that will enter the arena with a +1 counter on it.

If cards and tokens you own lose and can’t gain names (e.g. Amnesia), effects that use names will fail to find/identify objects with any specified names. Under this effect, your first attack with Spectral Shield in its name you activate will not cost less to activate.
