Here's the issue I have with both the LOTR and Dr who sets, as well as the 40k set, which comes from my inexperience probably (only been playing about 4 years). Will these sets both just be legal forever minus a few cards they might ban? I feel like if wotc adds too much 3rd party IP it could dilute the lore/universe they've made, no?

Also, im very curious story wise where it goes after MOM. I want Ajani to pop off now that he's healed and get some more sweet lifegain cards printed (I started during the heliod/ajani meta on arena)
