in the same way ecr spanks you if you like to play the game this will stop players from buying single bcx copies to play with and force them to rent maxed copies only.
i play in gold/diamond modern and don't wish to spend $39000 on maxed copies of untamed and $9000 on dice or put money into the game every 2 days to rent them. for this reason i buy at least 1 bcx of all monsters and level key abilities . this will just add to the barrier of entry for new players
