We have a variety of ways to keep triggering Kardur: the most common is by making token copies of Kardur with cards like Jaxis, the Troublemaker and Orthion, Hero of Lavabrink which trigger his mega goad before dying, but we also have bounce with Skull Collector and reanimate/blink with Rescue from the Underworld
The blitz effect (sacrifice at the end of the turn and draw a card when it dies) also only applies if the creature was cast by paying the blitz cost, not if its copied
This dog commander is also great with living weapons like Batterskull and sagas you want to get the first two chapters of, like Elspeth Conquers Death
Each section will be broken into what Im going to call mandatory and flex. Cards in the mandatory are cards that I think should be in the deck 99% of the time (I suppose there technically can be metagames where you cut them, but I personally havent encountered them)
The very nature of PolymorphPolymorph effects like Palani's generally pushes you towards building your deck with a low number of highly powerful targets in the 99
The next time I turned it back on, I had to start from the beginning
