Creatures (3) Planeswalkers (8) Lands (35) Spells (34) Part of the benefit, of course, is that its a reliable legendary artifact, ensuring our Karns Temporal Sundering is live (though we do have a lot of planeswalkers to help there, too)
Treat these as reference ranges for a packs specific set and print run never as a universal cutoff
If I had to pull out anything interesting to say, its a 5-mana spell that sometimes only charges 2 mana, which might matter for cards like Vial Smasher the Fierce or Rain of Riches
Do that and you should be able to defeat Robert easily
Strange, which was given out at Conventions as a promo
If you arent able to find either of these cards or are looking for a third card that does Loyal Warhounds job a little less efficiently, you should also consider picking up Scouting Hawk from Commander Legends: Battle for Baldurs Gate
