Emblems and The Ring
Every emblem's real text, plus a pinned tracker for the Ring-bearer.

Nobody remembers the exact wording of an emblem three turns after it was created, and The Ring has the same problem. Manatable has a searchable catalogue of roughly 90 real planeswalker emblems, generated from Scryfall, so the pod can look one up in the app instead of reaching for Gatherer.
The emblem catalogue
Each emblem renders its full oracle and reminder text alongside the card art, so there is nothing to argue about once it is on the battlefield. A search bar and "Popular" quick-add chips get the one you want onto the table in a couple of taps.

The Ring
The Ring tempts you differently depending on how many times you have already succumbed, which makes your temptation level (I through IV) worth tracking properly. Manatable pins a tracker that spells out each level's ability as the Ring-bearer advances, with a one-tap "take off the Ring" reset for when it changes hands.

Two mechanics people always misremember
Emblems and The Ring both sit on the board for a long time and both go fuzzy fast. Having the real text on the table means the game keeps moving while somebody checks.
Shared panel, every mode
Emblems use the same panel logic as counters and tokens, and they track identically whichever of the game modes you are playing, Standard or Kingdoms.
