1) Technically you only need to cast Idol of Pestilence to force the opponent to come to you. The Tournament rules say that whoever took more damage in 75 minutes is defeated if there is not a conclusive (KO) outcome. I think the greatest strength of Idol is that it is effectively 1 damage with unlimited range, and puts the onus on your opponent.
That would be correct under the old tournament rules. At this past tournament we were testing out Arcane Wonders new, experimental tie breaker system.
Game Points Awarded as follows:
5 Points Defeat the enemy mage.
3 Points Modified Win – the play with the greatest Health Total i.e. Life Total – Damage
1 Point Draw – (the player that had the lower Health Total)
0 Points Loss
Tournament Points and Determining a Winner
Add up the total number of points, the player with the most wins. In the event of a tie, look at strength of schedule i.e. average the total number of points earned by each players’ opponents. The player whose opponents have the greatest number of points is the winner.
Total damage is no longer tracked for tie breaking purposes. It is now the remaining health that determines who is the modified winner.
In any event, I agree that Idol of Pestilence is a great card for the Necromancer.
