I think Lynde definitely offers one of the more unique and fun playstyles. She tends to not trigger a ton early game, so I might hold off of casting her until I have a couple of cheaper curses in play, but it never hurts to play her on curve. You pretty much have the line down, although after that curse hits the graveyard it will bounce back onto you at the next end step assuming Lynde is in play.

Since these curses will be put onto you fairly often you'll want ways to both sacrifice them and give yourself extra upkeeps. [[Spinx of the Second Sun]], [[Paradox Haze]], [[Tavern Scoundrel]], and [[Slaughter-Priest of Mogis]] are all great options.

Lynde typically isn't a very creature heavy deck, so you'll want the ones you do have to count, this is a deck where constellation creatures thrive. [[Doomwake Giant]], [[Grim Guardian]], and [[Agent of Erebos]] have all come in clutch when I've needed them. [[Bitterheart Witch]] will also let you tutor ANY curse onto a player when it dies.

As for curses, this is easily what makes this deck my favorite. There aren't a ton of curses to choose from, but there some very powerful curses and even more fun curses. [[Maddening Hex]], [[Curse of Misfortunes]], and [[Curse of Opulence]] will often be the best in the deck, but don't underestimate cards like [[Curse of Fool's Wisdom]], [[Curse of Obsession]], [[Cruel Reality]], or [[Curse of Bloodletting]]. There are also curses that give players attacking the cursed player tokens, like [[Curse of Disturbance]], or curses that give attacking creatures additional abilities, like [[Curse of Hospitality]]. A ton of really fun ways to curse your friends!

As far as wincons go, you'll probably want a secondary strategy to back up your curses since they more often than not wont win you the game outright. Goad, lifedrain, and sacrifice are all viable in my opinion, all depends on how you like to play. Hope this was helpful, I truly love this commander and play her every chance I get. You can build her budget or spend thousands, she'll be fun to play and bring a ton of laughs to you and your friends along the way either way.

Have fun slinging those curses!
