Take for example this Charizard V card that was posted by a redditor named mathmannix: Notice that this Charizard has a whopping 500 damage for its Wild flames attack, with an awkward description saying Attack with igniting fire, and all the elves of the opponent will be burned. Unless youre playing Magic the Gathering, youll never encounter any elves when playing Pokemon TCG
Besides, if youre attacking aggressively enough, how much can your opponent even attack you back to punish you for the life loss from Bobs ability
Morphling (Saga/Legacy/Destiny) Every format has a couple of bomb rares where *THAT CARD* is the one card they want to open
You can recast your Control Magic on the better target and your foe must spend mana again to recast their creature
If possible, the best combination in my opinion is to have Rageblood Shaman, Kragma Warcaller, Neheb, the Worthy, and Fanatic of Mogis
