The reasoning behind this is that discard is already annoying
Delighted Sightseer is from last set, but you should be able to trade for a couple more he works well here
In between those is Zantetsuken, an ability that means "Whenever this creature deals combat damage to a player, that player loses the game." Thats just nasty, especially if you find a way to give Odin Trample or Flying
Getting to get yourself elite enters-the-battlefield triggers by copying huge haymakers from the opponents can help swing the game in your favor
Even if the opponent plays a big character, the deck has several ways to increase the power of your characters, and them fight on the same level of any threat
At its worst, it's still a 6 mana costed card with 7/6, Trample and Haste, so it's still a strong card without its ability
