It's alright-ish, but I've seen it do really retarded things (using it in control mode), namely :
- Using a Truesilver on face rather than keeping it for a potential minion (when there wasn't a second one available in hand).
- Using a Trusilver on a minion when using it on face would have meant a victory (6HP left on the enemy hero, Truesilver with 2 charges left, still lost the game).
- Silencing and THEN polymorphing a minion.
- Using the Acidic Swamp Ooze casually as a regular minion when the enemy has potential weapons left.
- Using the last consecration to clear a 3/1 minion (first one almost wiped the board, enemy had only the said minion on the board with no cards in hand. The last remaining 3/1 wasn't a threat to my dominant board state).
- Using two Power Blessings on an enemy minion for nothing (not part of any combo)
