Tymna itself is already strong, and just dealing damage to a single player, paying 1 life, and drawing a card is what you want to do anyway
Let's take a look at the numbers that will factor into our decisions: Cost: Cost to pull the card: $120 Charizard Ultra Premium Collection Box Grading: Bulk grading with CGC: $15 (must be submitted in larger lot) Shipping to and from grading (part of larger lot): $2 Total cost to own & grade: $137.00 Values: Raw Value (based on TCG Player last sold prices): Near Mint $500 average CGC 10 last sold on eBay average: $1000 CGC 9.5 last sold on eBay average: $700 CGC 9 last sold on eBay average: $500 CGC 8.5 last sold on eBay average: $400 As you can see from the market values, if the card hits a 9 or lower, I might be better off selling the card raw (if that is my ultimate goal with the card)
If you are not sure what to buy, start with Play Boosters
Certain groups of cards can also be a design knob with a strong effect on power level, even if the individual cards arent outliers
So this one is really about using your graveyard as a resource to get bonus effects and/or abilities
How do I know which sets are legal
