Rare isnt Rare but Still is Rare - Wild Cards
Thank you for realising some spells are not really the rarity that they are printed at.
3 points:
1) For all spells, you should be able to craft them at the lowest rarity they are available for.
That is, Persist isnt a mythic but should be a rare wildcard.
2) If in a future set, Persist is printed at uncommon or lower, please refund players based on this. (This should apply to every card.)
3) Please refund players who crafted cards before this change to the crafting/style policy and commonality.
Say if you have 1 to 4 copies of Spirebluff Canal (KLD #249) but prefer the OTJ #304 version, there was a point in time you probably had 8 rare wildcards tied up. Now you only need a minimum of 4 rare wildcards from any of the fast land sets to get a playset of the desired style.
Instead this should be a matter of style selection. OTJ #304, OTJ #270 and KLD #249 should all be seen as styles. Thus a player has 4 rare wild cards tied up so they can just select the card treatment (depending on the deck vibes).
