Discuss the possibility of Shandera being banned or not. Make intelligent posts, avoid talking about things you didn't test, especially if they're from 4th gen. Try finding counters, checks, and threats to Shandera, try to give an estimate of its power, and what it does very well. Then say your opinion on its tiering. If a consensus is reached after several days of discussion, backed by people who do well on the ladder, then it'll probably be adopted. Don't forget this is for the Dream World tier.
