Emrakul, the Aeons Torn is currently the #1 Alternate Endgame Card in favor for this deck. It is listed (for now) in the sideboard, so that its capabilities in game can be directly compared to that of the card it is expecting to replace: Riptide Replicator. The Eldrazi creature will remain on the sideboard until a definitive consensus has been reached regarding the final identity of the second endgame piece.

Wirewood Lodge appears (to me) like a nice catalyst to the mana acceleration strategy that this deck employs. When used with Priest of Titania, Elvish Archdruid, or Rofellos, Llanowar Emissary, this land can severely increase the amount of available mana. These resources can then be channeled into reinforcing nicely the abilities of Joraga Warcaller, Riptide Replicator, or even the aforementioned Genesis Wave.

A potent finisher because of Strength of the Tajuru's Instant properties, this combo was inspired by the generous ideas of early commentator pludas. Gaea's CradleGC, Priest of Titania, and Elvish Archdruid provide the mechanism of "representing" the total number of Elves under your control, while Strength of the Tajuru completes the conversion of that number into '+1/+1' counters for Joraga Warcaller. This newfound strength is then distributed by the creature to all other Elves you control, thus substituting the effect of Coat of Arms.

Using Strength of the Tajuru as the powering engine creates the most "permanent" alternative of the Coat of Arms effect, since '+1/+1' counters are typically much harder to remove than artifacts (Coat of Arms) or creatures (Joraga Warcaller). This combo uses the same mana components of the previous strategy, and channels it through this powerful instant. While one member of the Gaea's CradleGC-Priest of Titania-Elvish Archdruid family supplies the kicker, another provides the casting cost needed to load on the appropriate amount of counters.

This card is a popular staple in many Elf decks. Its usefulness as a draw engine has transformed it into the holy grail of almost every Elf player out there.

Taking advantage of Heritage Druid's existence in the deck, Glimpse of Nature completes a combo that puts numerous creatures from your deck onto the battlefield.

The card-drawing engine that this sorcery spell initiates is a force to be reckoned with, and is an excellent reason why the card should belong to this deck.

Post-Innistrad Reconsideration: In hindsight, Glimpse of Nature still places as a wonderful selection, and ranks as one of my top choices for the acceleration-dedicated slot of this deck. However, as mentioned by Jimmeh92, I believe that Glimpse of Nature doesn't exactly fit the build and structure of this deck. However, it is a priceless, essential card nevertheless, and thus I believe it rightfully belongs in the backseat, or the hidden 'Acquireboard' section of the card list. This section of the description will still remain as an explanation of why I previously chose to include this card in past revisions of the deck.

For example, the listed match of cards above, Riptide Replicator and Rhys the Redeemed, can be used to replicate a powerful 'X/X' Super Elf token very efficiently. Assuming that you have achieved appropriate mana acceleration, these super tokens can be generated at a rate of 2 on the first turn, 6 on the second, 14, 30, 62, etc. Sure it's not as mana efficient as some of the other combos, but through this method, the essential function of a Coat of Arms can be attained.

Post-Revisions Update: Since the deck's third revision, the card Riptide Replicator has been moved to its backseat. However, I believe that it is still a competent alternative to consider when brainstorming for possible card changes. As such, this card will remain in the hidden, 'Acquireboard' section of the deck list. This paragraph of the description will still remain as an explanation of why I previously chose to include this card in past revisions of the deck.

As the third and final example of the deck's volatility, I would like to mention the multiple uses of the win-con Strength of the Tajuru in a game utilizing this particular stack of cards. As one of the two endgame cards employed in this deck, the ability to Permanently strengthen up Any Number of target creatures grants this spell an unprecedented level of power. As an Instant, it can give any one creature the final increment of brawn you need in order to finish off your opponent after an extremely close game. When paired with Joraga Warcaller], as shown above, the card unleashes an Elvish hell onto the battlefield that tortures your opponent to death from the moment he/she realizes what you have just amassed. When used hardcore with Priest of Titania or Elvish Archdruid for its multi-kicker ability, with the additional mana price paid in full by either of the two latter Elves, this card can substitute for Coat of Arms at a reduced effectiveness (or greater, depending on the situation). The volatility of this endgame element anchors its usefulness in an acceleration deck such as this.

You can probably already figure out how Gaea's CradleGC can work symbiotically with the following cards.

If you also happen to have Priest of Titania, Elvish Archdruid, Heritage Druid, and/or Rofellos, Llanowar Emissary stocked up on this artifact, Riptide Replicator can become your swinging creature of doom. For the final touch, tack on Rhys the Redeemed and you'll have an army of death in no time!

Post-Revisions Update: Since the deck's third revision, the card Riptide Replicator has been moved to its backseat. However, I believe that it is still a competent alternative to consider when brainstorming for possible card changes. As such, this card will remain in the hidden, 'Acquireboard' section of the deck list. This paragraph of the description will still remain as an explanation of why I previously chose to include this card in past revisions of the deck.

As a mighty reinforcement to the Priest of Titania/Elvish Archdruid + Strength of the Tajuru combo, Gaea's CradleGC pays in full any kicker cost inherited from using Strength of the Tajuru, allowing you to use either Elvish Archdruid or Priest of Titania to pay directly into the number of '+1/+1' counters available for distribution. Furthermore, the combo would replicate the effect of a more permanent Coat of Arms, allowing you to take your Elves to the battlefield and win!

This card has such a potential that I believe it deserves its own mini-section. It's also a new addition to the deck, so I figured that highlighting this change will reveal my thought process a little more clearly.

Aluren brings an Enormous level of creature and mana acceleration to the table. As the new substitute for Elvish Guidance, which was the then substitute for Earthcraft, I believe that the single non-creature, acceleration-dedicated card slot has finally found its winning candidate. In addition to freeing All creature cards of the deck from any casting cost, the 'Flash' attribute given by Aluren grants every one of your Elves a 'Pseudo-Haste' ability. Simply play your creatures during the end phase of your opponent's round, and you are free to attack him relentlessly (or activate tapping abilities) on your immediate turn. Whether insta-blocking in an emergency situation, setting a Power-Fest trap on your enemy using Joraga Warcaller, or simply clearing your hand of useful cards so that you can use Slate of Ancestry's ability with a peace of mind, the acceleration card Aluren gives you an advantage unlike any other. Of course, these abilities are given to your opponent as well, but it is more than likely that you can make better use of its effects than the guy/gal sitting on the other side of the table. In any event, there's only one copy of the card on the decklist, and since you are the insightful, observant Magic player that your parents made you out to be, you will be able to assess the situation appropriately and make the right decision as to whether you should play the enchantment for its advantages or discard it for a better hand using Slate of Ancestry.

Post-Innistrad Reconsideration: In hindsight, Aluren still places as a wonderful selection, and ranks as one of my top choices for the acceleration-dedicated slot of this deck. However, in light of the ultra potential of cards such as Parallel Lives and Doubling Season (as kindly suggested by graft, thanks!), I believe that Aluren rightfully belongs in the backseat, or the hidden 'Acquireboard' section of this card list. This section of the description will still remain as an explanation of why I previously chose to include this card in past revisions of the deck.
