Yes this is exactly the point !
If somebody has maxed out a regular-foil-common card he has burned 399 cards and reduced the supply of cards by 99,75% - Why he should get punished for this by beeing annoyed with hundreds of useless copies of this cards and why splinterlands is not able to offer something for him ?
I done already a suggestion but obvisiouly splinterlands doesn't care at all:
"Once a soulbound-reward-card is maxed, it will be removed from the pool of cards this player can get (can still get gold foil version if not maxed) . If all regular-foil-reward-cards are maxed the player should get only goldfoil-reward-cards and if all regular-foil & gold-foil-reward-cards are maxed out he should get another soulbound ressource (f.e. merrits, blood or power stones, potions, dec-b)."

No reaction from splinterlands at all, same as for the suggestions 1551 to 1564 - why they start such a site when they obvisiouly aren't interested at all in feedback ?
