The first thing you do when activating an ability, is to put it on the stack. Which will look like this
Yahenni Indestructible
Then, you pay costs, in this case, you are sacrificing CoA. You have now completed the activation of Yahenni and the ability is on the stack. Before anyone can do anything else, CoA triggers as it was put into the GY. That trigger goes on top of the stack, which now looks like this:
CoA Destroy
Yahenni Indestructible
Provided no one wants to do anything else, we start with the topmost action on the stack, which is the CoA that will cause a lot of destruction. Then Yahenni would give itself indestructible if it were still around, but it is very much dead in the GY by then.
Frankly, I blame MaRo, Stoddard and the FFL.
When was the last time we had a Standard enviroment without "mistakes"? ODY-ONS block?
At some point Hasbro has to start noticing it's not the cards, but the people making the cards, who need to go.
You realize MaRo is only the first step right? It goes through an entire different department (Development) before it gets finalized. It was Development that pushed JtMS to absurdity as an example.
When declaring attackers, the attacking player may choose to either attack the player, or a planeswalker that player controls. If the Vraska player uses the +1 on Vraska, any creature that attacks Vraska and deals damage to her, will be destroyed.
Really any small set will have had a smaller print run as it would have only been around for a few months compared to the large set being printed for the entire block
It depends on the card you are using to blink. If you are using something like Momentary Blink then no, since the entire card has to resolve before you get a chance to do anything
Yes. Parallel Lives and its kin just alter how many tokens are produced from the source.
No. The Biomancer has a replacement effect that modifies how a creature enters the field. Since the Biomancer and the Witness are returned at the same time, it will not be able to affect the Witness.
Packleaders are different, since they are standard ETB triggers. Each Packleader will see the other and you will draw 2 cards
Magic works with priority. A player can only cast a spell or activate an ability when they have priority.
If I play a Jace and it resolves, I will have priority again. If I activate one of Jaces abilities, the cost is adding or removing loyalty counters. Players cannot respond to costs. So by the time the Lightning Bolt can be cast, Jace will have more than enough loyalty counters to survive the 3 damage.
However, you cannot use an ability when you dont have permission to. In order to activate the ability of a planeswalker, the stack needs to be empty and you need to have priority. So if for some reason I forget to use Jace right away, and do something else instead, I cannot then use the +2 ability on Jace after the Lightning Bolt has been cast
Your friends are correct on this one. Gisela only triggers at the beginning of the end step, and she was currently in exile when that point of time happened. You will have to wait until your next end step to Gisela to trigger again if you meet the requirements still
That is correct. The first thing that happens in the upkeep step is that all abilities that trigger at the start go on the stack. So the latest you could respond will be the end step before your turn begins
The token will be a 6/6. When you put a copy of something on the 'field, you copy exactly what the card looks like without any added bonuses. Your Mimeoplasm/Mimic/Dragon is on the field looking like the dragon.
As for Commander damage, the copy wont deal commander damage. Commander-ness is something that is true about a card.
When you have the Blackguard in play, there will never be a moment when another Rogue enters the field when it doesnt have a +1 counter on it

The land would have the following 2 abilities
and
You would need to choose which of those abilities to use whenever you tapped the land
No. The Biomancer has a replacement effect that modifies how a creature enters the field. Since the Biomancer and the Witness are returned at the same time, it will not be able to affect the Witness.

The land very obviously came into play tapped at this point. He played it, and then scooped the game
