Is it wise to use Timber as a 1 star filler in any deck.
Cancel Leader works if both you and your opponent have one right? So not only is he a 5/2, but he makes their Hugo or Ambre less intimidating. And using level 1 Timber leaves room for other great clan cards.
If I'm wrong about cancel Leader (I only use Vasneer in Training...), then sorry, but this seems like a good idea to me.
No, cancel Leader only cancels your leaders' bonuses if you have more than one in hand.
Your opponent's leaders are unaffected.
