The Familiar is very nice to add for familiars and will be a staple for any new Level 3 Spellcaster Ritual Deck.
Weaknesses: Situational, Gringdijel will not be used still given its awkwardness.
Strengths: Generate advantage while also changing attributes so very nice. I think that its Main Deck ATK buff wont be used very much, but it will be used for its discard effect much more. I think the Ritual Spell needs a buff but it might not need it given it will generate advantage.
