Terisian mindbreaker bug
Terisian Mindbreaker's attack ability is supposed to mill "half" an opponent's library when it attacks. The bug that i encountered is that half of my 60 card library was milled every attack. What shouldve happened was mill ~30 cards first attack, ~15 cards on the second attack, ~7 cards on the third attack, etc.
I lost after the second attack because i was required to mill 30 cards two turns in a row. This has been a problem as evident in the many postings complaining about it before me. I chose to repost the issue mostly because the previous postings are mostly incoherent whinings with little in the way of clearly reporting the issue.
It has been a problem, yet arena devs continue to ignore it for two simple reasons:
1) this issue is not regularly exploited in competitive tournaments
2) WotC wont fix recognize bug complaints in this forum unless there is a high number of other people marking it as critical. (This is inefficient as the bug exists regardless of whether or not people respond to my report).
