I did Breloom because he's my favorite pokemon, mainly because it was the best pokemon I had in my first pokemon playthrough, being Emerald
I was a big fan of Maul of the Skyclaves, which had a very similar feel: White equipment for three mana, attaches for free when it enters the battlefield, four mana to equip, +2 power and flying
Another time, I just needed one extra turn to properly equip my Pikachu ex, so I used Sabrina to stall my opponent just one more turn
Anvil of Bogardan also does a decent Howling Mine impression and would see more play if it wasnt so expensive
By offering a reward for aggression directed elsewhere, this stands out among red Auras for MTG by effectively paying the rest of the table to ignore you and focus on a common rival
Cards similar to Writhing Necromass include Ghoultree
