The Bird creature subtype has plenty of cards from older sets that might suddenly matter more with Zinnia - it's worth looking through resources like Gatherer to find them
For Yshtola, it came down to a mix of popularity of the character as well as being a spellcaster, her story and character development offered a wide range of abilities and moments to pull from to lead the deck
The latest Magic: The Gathering set feels like a powerhouse overall but, with its focus on legendary creatures, its hard not to feel like its geared for Commander players especially
Thats much more useful in your average game than copying enchantments, but it also has a less exciting ceiling
This allows you to immediately dole out a good chunk of damage and threaten your opponents with commander damage
You could be really unpleasant and run with poison counters, or create a superfriends deck full of planeswalkers.Whatever route you go, you're probably going to want more effects that proliferate, so cards like Ezuri, Stalker of Spheres and Tekuthal, Inquiry Dominus are a perfect fit
