Greater Good Card draw is good, and many decks can benefit from dumping cards into their graveyard
Typically, I'm immune to nostalgia bait
This was preferred in combo based decks as, though it only got you two cards, it lets you pick from 7 cards
Whenever you cast a spell that targets a creature you dont control, Legolas deals damage equal to its power to up to one target creature
The potential for colorless mana limited only by your life total is decidedly spicy, and limiting it to spells cast from a graveyard is a good way to keep it in check
We just got a fair chunk of WB Knight Tribal support in Dominaria led by Aryel, Knight of Windgrace, so it's strange that the very next set would throw some nice Knight Tribal support
