When it enters you can discard and then draw two, note that's may and then sac with three to make a 2/2 tapped Robot
I would not overreact to the perception of this set as "bad" and buy everything that isnt awful, but its safer than normal to preorder or trade for the significant cards in this set than it was for Return to Ravnica or Theros
Archangel of Tithes, Archangel Avacyn (with trigger on the stack), Mindwrack Demon, and Dragonlord Silumgar are all prime targets that are usually much more difficult for a red deck to deal with
Also like Poisoned, Pokmon can't have two Burned tokens at once - if it gets burned again, the new token replaces the old one
I especially love Fertilid here
Thats still a solid gain, but its also a best case scenario that the trash RL cards are unlikely to approach
