Extended Glimpse Elves deck
The Elves deck in Extended is majorly focus on this card Glimpse of nature this is the card that can provide a huge amount of cards for Elves is a creature base deck
As for mana, the deck offers heritage druid and Nettle Sentinel inter-action. By tapping Elves--> produce mana--> play Elves --> Untap Nettle Sentinel --> tap them to get more mana. Once this action is going, the player can smoothly draw his/her entire deck since there are way too many mana floating shortly after repeating this process.
Always, things won't get so smooth so Elvish Visionary and Wirewood Symbiote interaction (bounce Elvish Visionary with Wirewood Symbiote re-cast it and draw a card) sometimes will come into play to help and this action turns out to be powerful as long as Druid-Sentinel mana engine works.
For spells, the deck offer Summoner's pact for tutor Chord of calling players in PT Berlin 2008 use this to find hate cards for mirror match weird harvest when too many manas are floating, use this to find whatever action you want to trigger, but usually it is Nettle Sentinel and Regal Force sometimes thoughtseize along with Gilt-Leaf Palace.
The other key card to complete combo is Birchlore Rangers this card provide any color of mana you wish and make every card be playable inside this deck.
