If opponent attacks with 3/3 with trample, and I block with 3/2 no abilities, does the trampler get killed and I lose one life or is the trampler just killed without trampling through?
The trampler and blocker would both die and you would (potentially) take 1 damage, resulting is losing 1 life. The attacker can choose to deal all 3 damage to the blocker if they want, but there usually very little reason to do that.
Here is the relevant rule for Trample:
702.19b The controller of an attacking creature with trample first assigns damage to the creature(s) blocking it. Once all those blocking creatures are assigned lethal damage, any remaining damage is assigned as its controller chooses among those blocking creatures and the player or planeswalker the creature is attacking. When checking for assigned lethal damage, take into account damage already marked on the creature and damage from other creatures that’s being assigned during the same combat damage step, but not any abilities or effects that might change the amount of damage that’s actually dealt. The attacking creature’s controller need not assign lethal damage to all those blocking creatures but in that case can’t assign any damage to the player or planeswalker it’s attacking
Your opponent chooses if you get hit for one. After you declare the blocks he assigns the damage, and must do at least leathal to the blocking creatures. He can so all 3 to the blocker or 2 to it and 1 to you
If people are sick of reading about stuff just stop taking part. You have 100% control over what you read. Simic Ascendancy isn't going to get banned just because you didn't tell someone to shut up on the internet.
Thank you.
