In Tellah, Great Sages case, Im very interested in the draw-two ability
3 Argothian Elder, and Ashaya, Soul of the Wild Any infinite combo that uses a potential commander is great, and Ashaya, Soul of the Wild is a fantastic commander
As far as opponents go, Dragonite doesnt have any elemental weaknesses but an Electric-type deck can chew through your Articuno ex stall faster than usual which may put you on the back foot
Though your own critters are going to be caught in the crossfire, a Ygra deck is likely built with disposable (or indestructible) creatures in mind, keeping important cards alive with Gyome Master Chef or profiting from their destruction with Marionette Apprentice
It's also a very playable card thanks to its Shift cost and the impactful abilities
Then, if I actually want the cards, Id just pick up the singles on the secondary market
