The first is as Rezzahan has described, with using the Channel ability of Eiganjo, Seat of the Empire in the declare attackers step to avoid the Ninjutsu.
Or Your opponent could wait until the declare blockers step, by allowing you to ninjutsu, then using the Eiganjo on the new Ninja. This is because the attacker has priority, so needs to Ninjutsu before their opponent can react, but the opponent still gets priority to act before combat damage can be afflicted, and therefore could take out a bigger threat (just depends on what left and what came in).
Card Slinger J, you dont seem to realize how any of these cards work.
Here is a scenario for you, using your board state mentioned:
You have Toski, enchanted with lure and Druid's Call in play. Your opponent has a 3/3 and a 2/2 (no abilities to keep this simple).
Its your turn and attack with Toski (as he has too attack every turn if untapped).
Your opponent has to block Toski with both the 3/3 and 2/2 due to lure, so does so. Damage resolves and Toski receives 5 damage total and you have assigned 1 damage to one of his creatures (not relevant for any outcome here), you then make 5x 1/1 Squirrel tokens. (also no cards are drawn as no combat damage was assigned to your opponent). You decide to end turn and play passes to your oppoenent.
Your opponent decides to play two 1/1 creatures (again with no abilities) and passes the turn.
You start your turn as normal and decide to move to the combat step. You decide to attack with all 6 creatures (again forced to attack with Toski), and again due to Lure, all of your opponents creatures must block Toski and does so, meaning Toski is blocked by a 3/3, 2/2 and 2x 1/1 creatures and your other 5x Squirrels remain unblocked (they do not need evasion for this to be true). Again combat damage is assigned, 7 damage to Toski and you decide to assign his one damage to one of the 1/1's. Meanwhile your 5x Squirrels assign damage to the opponent.
The results of the assigned damage means that due to Druid's Call, you receive 7x more 1/1 Squirrel tokens, your opponents 1/1 that was assigned damage dies and you draw 5 cards for the 5 attacks that landed on your opponent from your Squirrel tokens.
Its possible that the “White creature that can make an opponent lose the game simply by attacking them no matter how much life they have”, could also be the same card as the “If it’s the third time” as in: If it's the third time that CARDNAME has attacked this turn/opponent, then attacked opponent loses the game.
Tack it onto a 1/1 then it would make it hard to do so.
I also thought of the 'this turn' part as I was typing this, but this seems a more red thing than white, and the 3 separate turns would be more white, though maybe not enough hoops to jump through.
EDIT: Another thought is that it could be: If it's the third time that CARDNAME is blocked, defending player loses the game.
It is also possible that as someone else has mentioned, this may not be a mono white creature and could be WR or WU.
@leslak, there are more references to that Circle.
The stones that Jace is surrounded by in he top left of the image you gave, as well as the half floating thing hes looking at too (probably a broken statue of the dipiction), though it looks like a toothy thing now. Also there is the small monument behind the trap he dodges too.
Its also possible that the creature Nahiri fights is what leads her to that orb she has floating, which those images also seem to depict. Maybe they were both (treasure) hunting the same thing and its that orb?

I hope that this clears things up.
