I like many of the others that have responded here, I think bots belong more in Wild than Modern. Modern to me is where the 'current' game scene is and for other TCGs it is what tournaments etc are based on. In this case I think keeping it largely human only is a good move.

The current Modern bots will have no issues moving into Wild and we will simply see a rental shift change of the types of cards they are renting out which should increase the value of Alpha/Beta etc since to my understanding bots are currently the largest body of card renters.

I do see the downside though in that those modern bots will now be taking part in the Wild SPS pool which means that in general all WILD battles will yield less SPS per battle as the total amount of SPS will be divided up into a now larger base of battles. This push however is probably good for the game however as it further incentivizes players to constantly 'reinvest' into new card sets.
