I come from an MTG background, where triggers are complicated - so I had to ask. Here's my reasoning - (assuming that things happen one after the other and not simultaneously, which would make my head hurt) if the targeting part of Sonnia's cast happens before the flip, then Tara's ability would probably trigger BEFORE the flip, thus there will be a bonus to WP and there will be a bonus flip. But can this trigger resolve before the flip is made? However, if the targeting and the flip are the same action, and the Heartless trigger hasn't really given the bonus when the flip is made, there can't be a bonus flip. Uhg, my head is starting to hurt already... I think I'm too much of a rules-arsehole to play this game, guys...
