I've noticed the lack of "bring back from the graveyard" makes the delve hooting mandrils quite useful later in the game. I am currently waiting on my LGS to build stock of Arbor colossus, Savage knuckleblade
I have play-tested this (keep in mind I have no standard players in my play group and am building this for FNM)
Vs. modern RDW with a splash of black (2-1)Game 1 wint1 elvish mystic > t2 heir of the wilds (down to 17 life) > t3 Ascendancy swing for 2 > t4 Bear's companion swing for 9 (down to 10 life, lost heir to burn) > t5 Nessian, no tribute, destroyed 1 of 2 potnl. blockers, deal 7, destroy blocker (down to 5 life) > Elvish mystic swing for 14 and wingame 2 lossno ascendancy, elvish out only at t2, used a charm to buy time but still lost due to lack of field presencegame 3 winsimilar to game 1, but my nessian was instantly burned as was my bear's companion (still got my bear tho) so I delved to summon hooting and swung for 15 to win
Vs. modern UW auras and flying creature protection (1-0)i was constantly being swung at with flying (i can't wait for arbor :p) so I dropped to 13 by t3. I used 2x charm to stop even more flyers from being created. I finally managed to get out nessian, tribute was not paid but protection from creatures so it was useless anyway, swung for 10 no blcokers were available to him, down to 9, lightning struck his flyer and another wall he had, swung for 10 and won.
I can already imaginge the benefit of arbor since a lot of flyers exist in all metas. also arbor is a great fatty even without the ability. I really think more ramp culd really boost the deck to a great height. Hopefully I can grab a set of voyaging satyr when I go to get my savage and arbor. Are golden hind or karametra's favor viable mana ramp cards if I can't find any voyaging?
