Card question: Shaman's Trance.

[Colossus]

I was wondering if anyone was clear on the interaction between this card and Yawgmoth's Will.

I played a game where I had it in the sideboard and wished for it when I had the will in hand at end of turn, then cast it and the will on the same turn.  I believe this allows me to play spells from my opponants graveyard, but it might be a bizarre interaction (are these two seperate replacement abilities, of which only one can take priority?)  

Thanks.

Please post rules questions in the rules forum.

The abilities of Shaman's Trance and Yawgmoth's Will combine to read:

"Until end of turn, you may play cards in your graveyard and in opponents' graveyards as if they were in your hand".

Plus the extra stuff about RFG'ing cards that would go to your graveyard and your opponents not being able to play cards from their graveyards.

Here is some additional info: Will + Trance

If you can get this to happen after your opponent plays a Lotus, that's infinite mana. Then again, if you need a random wishable card to make your yawgwill better, that's terrible.

This should have been in the rules forum, but since it's answered, I'll just close it.
