pokemon card ralts (Pulsing Aura #63/234, 1-Diamond) Colorless Teleportation Burst (20) Switch Ralts with 1 of your Benched Pokémon Ralts - 211/198 - SV01:

While Elder is a fine value card it is generally outclassed by planeswalkers who offer more threat and utility

The idea of it being imprinted on an Isochron Scepter is also a fun idea for a removal engine if (and thats a big if) you protect your boardstate

This would still "use up" the ability for the turn

3 Kaito Shizuki This Kamigawa planeswalker had yet to find an entirely perfect shell, but there was no doubting that this card has what it takes

Going from 5 mana to 8 in a turn is a big leap

Since these cards have been out of print for more than 20 years, even just finding them can be difficult and it is unlikely that many retailers will have them in stock
