Wrenn and 7 'Symbiosis' support causes freeze [Investigating]

TIMEWARP

Dear Team, please look into the interaction between the Symbiosis support created by Wrenn&7's ability and gem conversion due to (Urza) lands at the start of turn. This causes a freeze in some cases. I have had it happen 3 times now, but can't determine the exact cause. Hopefully you can reproducd and fix.

Hey, @TIMEWARP!

Got your report and we'll keep an eye on it. This kind of issue that happens once in a while is a bit hard to reproduce (consequently, hard to fix) so the more information on it the better.
Does it happen with other conversion effects too?

Please send us (as much as you can):

• decklist they were using during the soft lock
• which event were they playing
• an estimation of how long their game was running for when the soft lock occurred
• a screen capture of the game state.

If anyone else has seen this same problem, please let us know!

I have seen this reported several times over the last year or so in discord. I believe the consensus is the symbiosis trigger is trying to convert a crystalized gem and then freezing. This only happens with the Urza lands. If you have a beginning of the turn conversion effect that triggers symbiosis (like the one from Somberwald Sage) before the urza lands mana field becomes active for the turn, it does not seem to freeze. This could be why it's difficult to reproduce, because a lot of people run land conversion with Wrenn and Seven due to the nature of it's abilities.

@ambrosio191 Thanks a bunch!
This hypothesis will help us a lot.

Freeze on 1.2 I'm not using any seeds or urza lands as I know they are problematic... complete lock with missing gems after just making a three swap using this deck.

This ruined an easy perfect but more importantly cost my coalition a 2nd place finish in the event.

Here is the board state during the lock.
Not playing at the top of the hour ( as that is another thing to be avoided) game had not been running more than an hour..

This thread is for Wrenn and 7's symbiosis trigger causing freezes. These are screenshots of wrenn and realmbreaker. This should probably go in a separate thread to get addressed properly.
