I can understand why some of my colleagues might find it slightly depressing to see a physical card game go digital, that we're losing something tangible and obviously valuable by collecting Pokmon cards as digital images on our smartphones
Any time a card is both rare and has actual potential as a game piece, players can be pretty sure that it will end up being worth a good amount of money
Supporter cards are similar to item cards because they provide practical effects but can only be used once per turn
This allows them to attack the turn in which they were played, and it also provides artifact-based mana dorks such as Myrs to be used the turn they were cast, significantly improving their value
Thats why its so important to have backups within the 99 to take up the mantle when needed
Whether evoke's sacrifice ability triggers when the creature enters the battlefield depends on whether the spell's controller chose to pay the evoke cost, not whether they actually paid it (if it was reduced or otherwise altered by another ability, for example)
