Maester Seymour* Maester Seymour is still trying to appear nice here, but his monstrosity ability would reveal his true horror form, and the fact that he is a somewhat underwhelming creature until he shows his true face
The Praetors headlined the set, and would all have been powerful and valuable to see in the box I cracked
It may also include cards with no colors in their color identities
Exile this creature at the beginning of the next end step, then you may cast it from exile on a later turn.) If Rayblade Trooper dies at the same time as one or more creatures you control with +1/+1 counters on them, its second ability will trigger for each of those creatures
I have no idea what values for any of those might be, though
There are other card drawing artifacts that could be used, like Aladdins Lamp or Jandors Ring but neither of those are particularly playable, in my opinion
