Ok so when you summon Sylvan Messenger it suppose to get the next elf in your deck. And that works most of them time. I don’t know all the ways that this is bugged but if you cast Mantle of Web on the messenger and then cast another messenger it doesn’t get the next elf.
So I don’t know if it is because it has reach on it or if Mantle bugs it. It could be if you cast any enhancement on it then it won’t get the next one or maybe it is just when you cast Mantle on it. I really don’t have any other spells to cast on it to see what will happen.
As a side note, if you only have sylvan messenger as the only elf in your deck, and you cast it, it will fetch another one. You can stack that sucker up fast. I then cast Mantle on it to kill off all the attackers and that is how I found out the bug. If you can get one messenger you can chain them fast if you have the mana support cards.
The Dev has stated that your “deck” is 4 copies of each card, then when the deck gets emptied it builds a new deck. Did you have 4 copies out and try to grab the 5th one?
Basically if messenger is the only elf it will fetch another one until you have had(through normal draw or by elf fetch) 4 of them.
When you try to fetch the fifth the game reshuffles the deck and do not give another one.
From there on anyways if you manage go get another creature fetch effect it is possible to get messenger and start again the “4 elves” cycle cause new elves will be queued at end of the current remaining deck…
Is a quite complicated system to understand but that is how it works.
On a side note and mostly OT the fact that it does not draw the elf instantly after the reshuffle could be(since results in) a fast fix to talent of telepath infinite cycle(assuming it is the only spell in deck)
That with a single creature buffed by spells could lead to “infinite” damage
Talent looks at the first three cards on top of the deck, you pick one then if you cast again you only see one new card because the other two were the ones you put back in the first place, You would have to have a one card deck to play them infinitely.
I use messenger and you can fetch more than 4. Stop spreading this misinformation. You can draw more than 4 copies of something as well, just try a blue deck. http://imgur.com/EngYL4V
