From my understanding the SPS replacing CP doesn't benefit the Splinterlands company, it is a measure to create usecase for SPS with the hope of it impacting the price of SPS token which I think is a move that can have a positive price impact on the token but the approach is too drastic for the majority of the players to afford financially.
Cards still stand a chance to remain valuable, especially with Land where cards are needed for staking, we might end up needing more cards, especially for those that have lands and want to play the game competitively.
Overall I hope the SPS staking requirement is revisited to reasonably accommodate the player base.
We appreciate your input, many thanks for watching.
It probably make sense for people with probably 400k to 500k, massive money through rentals and all that.
