Winning Sand Worm in my battle quest, I was happy to see its high level of melee attack. I thought that with this card, I could easily destroy the frontline fighter of the enemy. To my dismay, I suffered loss I think two or three times using this card. And so I tried to explain my loss by saying that perhaps this monster is too slow.
And so as I continue my battles, I never used Sand Worm again. But this morning, I encountered an opponent who strategically placed Sand Worm at the last position. To my surprise, it could just destroy the enemy card with one strike. And so I realized that it was not its lack of speed that explained my loss, but the way I positioned it.
And so when the 99 mana limit came, I used life splinters and placed Shield Bearer at the frontline and Sand Worm at the back. I was happy to win the game over death splinters.
