But being Blue/White does fit in with his second ability
A green/white deck or a green/white/black deck should have plenty of single-target cards to help Legolas get +1/+1 counters or open fire, such as Shelob's Ambush, Morgul Knife-Wound, Bitter Downfall, Second Breakfast and Gollum's Bite
That's not all
8 Olaf, Friendly Snowman He Loves Warm Hugs The fun and silly sidekick of Frozen has an Amethyst card that may not look like a lot on the surface, but is a very helpful one to have in the early game
For that reason, I think its particularly worth it for Rakdos Goblin decks, which can easily run the above combo, while still being able to effectively use First Day of Class when its used in a more straightforward manner
Some effects will see too much play or maybe disrupt things too much
