Forum:Blackwhirlwind & Solidarity

If I have blackwhirlwind and solidarity on the field and summon a blackwing monster, which card activates first?

1. Will my monster be boosted by solidarity 1st and then I get to search for a monster or will I search and then get boosted?

2. Is the trigger of both cards simultaneous? Can I change the order by activating different ones at different order?

Thanks
