Tyrant-Thanatos Overlord

So far as I understand this situation, both would go onto the stack simultaneously.

Karmic Guide enters the battlefield with Animate Dead attached to it. SBAs are checked, and Animate Dead is removed. Then triggers are put onto the stack and active player receives priority. Both Animate Dead's "LTB" and Karmic Guide's ETB have triggered, and go on the stack simultaneously, meaning the player that controls both effects may choose what order to stack them in.

Now then, not only does this allow you to make Karmic Guide's ability resolve first, returning something like Kiki-Jiki before Karmic Guide is sacrificed. It also allows you to do the opposite, sacrifice Karmic Guide, then return a creature from your graveyard to the battlefield, at your option.

Neither Panharmonicon nor Naban, Dean of Iteration have triggered abilities. The only triggered ability that triggers when Silvergill Adept enters the battlefield is its own. Neban and Panharmonicon's abilities cause that ability to trigger an additional time each. Therefor, Silvergill triggers three times in total.

202.2d An object with one or more hybrid mana symbols and/or Phyrexian mana symbols in its mana cost is all of the colors of those mana symbols, in addition to any other colors the object might be.

Just for reference.

Yes.

Yeah, technically you have a lot of options here.

You can block either one and Cloudshift immediately, assuming neither creature has trample, the one you blocked is still considered blocked, and will deal no combat damage to you. Then when the other hits, its damage will be redirected to the giant.

Or, you could, as you suggested, block the first strike creature, then cloudshift after damage to redirect the remainder. The only real advantage to this though is that you'd deal 2 damage to their first strike attacker. Could be relevant, depending on other factors in the game.

Or, you could block neither. First strike damage would be redirected from you to the giant, then you can Cloudshift it, then normal damage would be redirected to it.

The one thing you can't really do here is have the giant deal its damage to the non-first strike creature without dying. If it were to block the non-first strike creature, the first strike creature's damage would be redirected to the giant, then if it were to fight the non-first striker, it would die, if you were to Cloudshift it, it would survive, but never have a chance to deal its combat damage.

No, hybrid cost cards are always both of their colors, at all times. Spitemare is a red and white creature card while in your hand/library/graveyard/exile; Spitemare is a red and white creature spell while on the stack; Spitemare is a red and white creature while on the battlefield; Spitemare's combat damage and damage from its ability are always a red and white source.

The only difference between something like Spitemare and something like Highspire Mantis in color/mana cost is that you can just pay 2RR, 2WW, or 2RW to cast Spitemare. Otherwise, it is in every way a red and white card.

714.4. If the number of lore counters on a Saga permanent is greater than or equal to its final chapter number, and it isnt the source of a chapter ability that has triggered but not yet left the stack, that Sagas controller sacrifices it. This state-based action doesnt use the stack.

So when a Saga's final chapter ability triggers, the saga isn't sacrificed until after that chapter ability is no longer on the stack. During this time, you would have priority to use any instant-speed spells and/or abilities to manipulate your Saga, while leaving the chapter ability completely unaffected on the stack.

Rescue it, Sentinel of the Pearl Trident, etc. You can even sacrifice it to an Auratog or what have you before it forces you to sacrifice itself.

RightyLefty why wouldn't you want to bounce lands in this deck?
