I want to make sure I am playing toss correctly regarding placed enhancements.
For Peace (EC), its own wording seems to 'protect' it from tossing itself since it says, "...toss all Enhancements played this battle..." so as long as you play it before the hero enters battle it isn't being targeted by the toss. However, Peace is the only placed enhancement with its own toss ability so its the only one worded this way so that leaves them open to being tossed depending on how the active toss ability is worded.
For cards such as Coliseum and Foreign Spearman, they are worded similarly to Peace and say, "...played in battle.." and "...played this battle..." respectively. So if my understanding is correct. Coliseum/FS would not toss any enhancement that was placed prior to entering battle.
Now we come to the cards that are more broad such as Goshen and The Cross. Each of these simply say to toss all enhancements that meet X requirement so it seems like they would target the placed enhancements that meet their criteria and thereby toss them.
Is my line of reasoning correct?
Peace (EC)
Place on your clay or blue Hero: When this Hero is in battle alone, toss all Enhancements played this battle. Cannot be interrupted.
Coliseum
Negate all protect abilities on cards in the Field of Battle. Toss all Enhancements played in battle that have “cannot be negated” in the special ability, or that have no special ability.
Goshen (LoC)
While a meek character (or a patriarch) is in battle, toss all Enhancements with a different brigade than the character using it. Protect your Reserve from opponents.
