However, there's a reason that you activate Tymna's ability at the beginning of your postcombat main phase. Her X ability is only concerned with combat damage, but the good news is, that means you're getting to often draw at least 1 card while only paying one life. She's like a super Phyrexian Arena, and that's a very good card. Getting 2 or 3 cards is pretty good also, but having to pay a life for each card is pretty fair.
Don't get me wrong. Tymna the Weaver is really good. In decks that already feature a good amount of lifegain, her ability is quite welcome. She's also a Partner Commander, meaning that there are a lot of ways to abuse her ability by adding more colors to the mix. But honestly, it's not that hard to deal combat damage in Commander. I am always happy with her being a conditional Phyrexian Arena on a stick. A 2/2 with lifelink is also perfectly acceptable. But I really think she needs a partner to unlock her full potential. Or maybe she's the Cleric Tribal Commander everyone was waiting for...
